About this game
RUBATOSIS is a rhythm fever dream where every boss fight breaks the rules.
Deflect notes. Dodge chaos. Stay focused as reality unravels.
Combat is everything.
Each fight has its own rhythm, mechanics, and voice. Every encounter is handcrafted to challenge your reflexes and attention.
Explore between battles.
Wander grounded, strange places. Talk to people who don’t always make sense, but often say more than they mean. Between fights, you pick at the edges of something bigger. Something you're not sure you understand.
"It’s the noise in your head and the beat in your chest.
About what breaks, and what’s left."
