Steam Next Fest occupies a specific and increasingly important role in indie gaming’s annual calendar. While the major pre-summer showcases — PlayStation State of Play, Xbox Game Showcase, Summer Game Fest — are built around announced AAA and mid-tier titles already known to the public, Steam Next Fest belongs to projects that haven’t yet found their audiences. The wishlist numbers accumulated during Next Fest, the user reviews from demo plays, and the word-of-mouth generated by streamers and content creators who discover games in these weeks can determine whether a project reaches its commercial goals or quietly disappears.
This year’s edition is the largest ever, and Korean indie games arrive with a striking range: experimental puzzle platformer, colony-simulation dungeon crawler, extraction RPG with antique shop framing, social deduction mystery, vintage cartoon roguelite, and forensic-investigation adventure. The genre diversity alone signals that Korean indie development has moved well beyond any single aesthetic or mechanical identity. Here’s what each project is doing and why it matters.
A puzzle that transforms space with light and shadow, ‘THANKS, LIGHT.’
Developer: Lightersgames | Release Window: September 2026 (PC / PS5)
The core rule of THANKS, LIGHT. It is elegant enough to explain in one sentence: illuminate a shadow with your flashlight, and it becomes a solid three-dimensional object; remove the light, and it returns to flat. From this single principle — and a healthy respect for what mirrors, lenses, and angles can do with light — Lightersgames has built a puzzle platformer that places itself deliberately in the lineage running from Portal through Superliminal to Viewfinder.
That lineage is the right context. These are among the most respected puzzle games of recent years, specifically because each found a genuinely novel spatial mechanic and explored it with rigor. THANKS, LIGHT. earns comparison to them not through marketing language but through design choice: a single elegant rule, applied with increasing complexity and creativity, teaching players through discovery rather than explanation.
The studio name — Lightersgames, meaning “people who shine light” — shares its conceptual foundation with the game’s mechanics. This kind of alignment between studio identity and game design suggests creative commitment rather than calculated branding.
Community evaluation has already landed on “intuitively understandable but deep,” — which is exactly the balance that distinguishes great puzzle design from puzzles that are either patronizingly simple or obtusely complex. The September 2026 release window is close enough that this Next Fest demo functions as final tuning before launch.
Dungeon Settlers, a dungeon crawler combining settlement and exploration
Developer: Can Opener | Release Window: September 10, 2026 (Steam Early Access)
The combination that Dungeon Settlers is attempting is genuinely ambitious: colony simulation (manage your settlement, keep your expedition members fed, housed, and psychologically stable) fused with dungeon crawler (send those same members into procedurally generated dungeons to acquire the resources that sustain the colony). The cycle between these two modes — surface management and underground risk — creates a dual vulnerability that neither pure colony games nor pure dungeon games can achieve.

The real-time-with-pause combat system positions the game precisely: not turn-based, which would slow the pacing, but not purely real-time either, which would overwhelm strategic decision-making. Pause when needed, issue commands, un-pause — this is the Baldur’s Gate school of tactical management, and it works well for games that need both emergent chaos and deliberate strategy.
The permadeath is crucial to both systems. When a dungeon member dies permanently, the colony loses not just combat capability but the character’s accumulated skills, traits, and social relationships. Losses propagate backward from the dungeon to the surface. This interconnection between modes — that underground failure has surface consequences — is what elevates the combination beyond two separate games occupying the same application.
The September 10 Early Access date gives Dungeon Settlers a clear commercial target from this Next Fest demo.
The buzzworthy title ‘Void Diver’ that surpassed 150,000 on the wishlist
Developer: Nemo Studio (under Road Complete) | Release Window: Second half of 2026 (Early Access)
Current Wishlists: 150,000+ | Demo Rating: 91% Very Positive
The numbers around VOID DIVER represent the most compelling pre-release validation of any Korean indie project at this Next Fest. 150,000+ wishlists before the expanded June demo launched, with 50,000 of those accumulated in just two weeks after the January demo release. A 91% Very Positive rating from those demo players. These are not small signals.
The concept earns attention. Players operate BALUSHA, an antique shop in a city consumed by anomalous phenomena. The shop’s business model: send “Divers” — treasure-hunting specialists — into the ever-changing Abyss dungeon to retrieve artifacts that can then be sold through the shop. The extraction loop (enter the dungeon, gather loot, extract successfully or lose everything) is wrapped in the antique shop management layer, creating a dual fantasy of the dangerous underground and the cozy surface operation that profits from it.
Up to 3-player cooperative play for the dungeon exploration adds the social dimension that extraction games thrive on. The shop management creates persistent investment in the operation that transcends individual runs. The procedurally generated dungeon structure ensures each dive presents new challenges.
The updated June demo adds shop management mechanics and Chapter 2 story content, giving Next Fest players a substantially expanded preview. With 150,000+ players already invested enough to wishlist, VOID DIVER‘s second half 2026 Early Access launch has one of the strongest pre-built audiences of any Korean indie project in this cycle.
If you don’t find the culprit, everyone loses, ‘Deadly Trick’
Developer: Final Blow | Release Window: TBA (Early Access planned)
Players: 5-8
Social deduction games — the genre that Among Us brought to mass awareness — have a structural problem. The equilibrium is unstable: experienced players dominate through accumulated knowledge of optimal play, and the randomness of role assignment creates situations that feel unfair regardless of skill. Deadly Trick is attempting a specific structural intervention.
The defining rule: if the murderer isn’t correctly identified, all innocent players lose. This shifts the genre’s incentives significantly. In most social deduction games, the pressure falls on the murderer to deceive; in Deadly Trick, the pressure falls equally on the innocents to reason correctly. A wrongful accusation doesn’t just waste resources — it ends the game with collective defeat.
The hidden “shadow” character who can interfere with the game or pass weapons to create new murderers adds a second layer of deception that maintains tension even after an initial accusation resolves. The unique abilities per character create information asymmetries that sustain replayability.
The subcultural art style and 5-8 player count targets friend groups who play together regularly — the audience that keeps social deduction games alive through sustained engagement rather than viral curiosity. Whether the mechanical innovations are sufficient to create a genuinely distinct experience from Among Us and Phasmophobia in the social deduction space will emerge from the Next Fest demo response.
Vintage cartoon-style roguelike, ‘Pengpong’
Developer: Sandy Floor | Release Window: Q3 2026
The creative origin story is good: a game jam prototype called “Pinball Survival” that evolved over multiple showcase appearances — Tokyo Game Show, BIC (Busan Indie Connect Festival) — into a full vampire survivors-like roguelite about a retired penguin hockey player fighting monsters. The concept has been refined through public development and showcase feedback into something with a clear identity.
The differentiating element is visual. Where most vampire-survival-like games use pixel art, fantasy aesthetics, or generic stylized visuals, PengPong commits to vintage cartoon aesthetics — the specific visual register of 1930s-1980s animation. This is not a minor aesthetic variation. The rubbery, exaggerated character animation, the specific color palettes, the particular way characters move in that era of animation — these create a distinctly different feeling from the mechanical foundation’s cousins in the bullet heaven space.
The contrast between the cute vintage cartoon protagonist and the escalating violence of wave survival is doing specific tonal work. The penguin is charming; the situation is increasingly absurd; the combination produces comedy that more earnest character designs couldn’t achieve.
Q3 2026 release positions PengPong for the summer gaming period, and the multiple showcase appearances suggest the team has been responsive to feedback about what’s working and what needs adjustment.
A forensic mystery adventure, ‘The Death at Fleming Manor’
Developer: SUPERTHUMb | Release Window: October 2026
Current Wishlists: 52,000+
Death at Fleming Manor earns its own full coverage elsewhere on indiegame.com, but its presence here matters in context: of the six Korean indie projects in this roundup, this is the one most directly engaging with a specifically underserved sub-genre of genuinely demanding deduction gaming.
The design innovation is the forensic documentation mechanic. Players don’t select from multiple-choice accusation options — they examine crime scene evidence, reason about cause and manner of death, and commit their conclusions to official death certificates. If the certificate is wrong, the truth is buried. This is the Return of the Obra Dinn model of requiring genuine deduction rather than optimal choice selection, applied to a 1959 English manor mystery with noir aesthetics drawn from classic detective comics and Agatha Christie illustration tradition.
The 52,000+ wishlists built through the recent Steam Detective Fest demonstrate that the forensic deduction angle is resonating specifically with the audience that has been hungry for more games in this style. The October 2026 full release makes this Next Fest demo the major pre-launch visibility moment.
The Broader Picture
Korean indie gaming’s Steam Next Fest presence in June 2026 demonstrates something worth stating explicitly: the scene has achieved genuine genre diversification. Experimental puzzle platformers, strategic colony-dungeon hybrids, extraction RPGs with unusual framing, social deduction innovations, visual sub-genre experiments in roguelites, and forensic mystery adventures — these are not the same game wearing different costumes.
For a Next Fest context specifically, genre diversity is a competitive advantage. Players browsing thousands of demos aren’t primarily looking for the best version of familiar things; they’re looking for things they haven’t seen before. Each of these six projects offers something specifically novel in its category, which positions them well in a discovery environment built around curiosity.
The next week of demo play, wishlist accumulation, and community reaction will generate real commercial signals. For projects like VOID DIVER (already at 150,000 wishlists) the Next Fest is about converting existing interest into confirmed early adopters. For projects still building their audiences, a week of global player engagement can determine whether the eventual release has the launch foundation it needs.
