The world fell apart when the music did. Alpha Nomos, the debut from four-person studio RibCage Games, is out now on PC (Steam), PlayStation 5, and Xbox Series X|S. It’s a rhythm action roguelite in which you fight on the beat, swinging weapons built from studio-recorded instruments, through a ruined world of circus puppets that have forgotten how to stop.
Players take control of Cello, battling puppets that have broken free of the music’s control. The core idea is to combine the precision of rhythm games with the randomness and replay pull of roguelites.
The look and sound are distinctive. Cartoon-style 3D graphics frame ruined cities and twisted circus stages in what the studio calls “puppetcore,” an aesthetic both eerie and charming. Instrument sounds recorded by real musicians in the studio add another layer of immersion.
A World Without Music, and Cello Still Listening
The music has collapsed and taken the world with it. The cities stand empty, and the circus puppets that once performed for audiences now hunt anything that moves. Cello and her friends are the last ones still listening to the music. As Cello, players set out to find what broke the world and what the music really is.
Combat is built around the beat. According to the developer, inputs are not automatically snapped to the rhythm; they register exactly when you press the button. Hitting on the beat is the skill.
The Steam page says players can build combos using on-beat hits as well as eighth notes and rests. Before playing, you can adjust a timing offset to calibrate the beat to your setup.
Real Recordings and Audio-Effect Power-Ups
Cello’s weapons are built from instrument sounds recorded by live musicians. The starting weapon, the Xyloblades, is a pair of xylophone-shaped blades. The developer says every attack carries a real performance, and as players settle into combat, the soundtrack builds up with them.
What keeps each run different is a set of power-ups inspired by audio effects. Combining Reverb, Flanger, Delay, and others changes both how Cello fights and how she sounds, so no two runs play out the same. The Maestro’s move shop lets players expand their arsenal.
A Puppetcore World
As the developer describes it, puppetcore is an atmosphere of clown faces, empty streets, and beauty that looks more twisted the longer you stare. Abandoned cities and puppets that have forgotten how to stop fill the circus.
According to the Steam page, the world also reacts to the music players create. The game was built in Unity, with FMOD used for audio.
A First Release, and Mixed Early Reviews
RibCage Games is an independent studio founded by four developers who left mobile game development to make PC games. Alpha Nomos is their first commercial release. The team released an expanded demo ahead of Steam Next Fest in June, announced console plans in July, and locked in the October 12 launch date in September.
Early critical reaction has been mixed. Raider King praised the concept and character design, but criticized weak early-game weapon damage, repetitive environments, technical problems, and long loading times.
Alpha Nomos costs $17.99, with a 10% discount on Steam for the first seven days after launch. Korean is supported for interface and subtitles; there is no Korean voice acting.
Who This Is For
Strong fit for: rhythm-game players who want strict, unassisted timing; roguelite fans curious about audio-driven build variety; anyone drawn to the creepy-cute puppetcore aesthetic; players who appreciate live-recorded instrumentation; Korean-language players, with interface and subtitle support.
Cautious fit for: players sensitive to technical issues or long load times, which the first review flagged; anyone who wants strong early-game momentum, given criticism of the opening weapons; those waiting for broader reviews, since only one critic review was available at the time of writing.
Less ideal for: players who struggle with precise rhythm input, since the game doesn’t auto-correct timing.
The Takeaway
Alpha Nomos has one of the most charming ideas in its genre: weapons that are literally instruments, power-ups that are literally audio effects, and a soundtrack you build by fighting well. Strict beat-based input and the puppetcore look give it a clear identity. The first review, though, suggests the execution hasn’t fully caught up, with slow early weapons, repetitive environments, and technical rough edges. For rhythm-roguelite fans, it’s worth watching how RibCage responds post-launch; for everyone else, waiting for more reviews or patches may be the safer beat to hit.
Out now on Steam, PS5, and Xbox Series X|S. $17.99 (10% off on Steam during launch week).
