Something's very wrong out there. Crashed ships. Escaped convicts. Lost vacationers. And somewhere in the cosmos, Matty Matter's friends are waiting to be rescued.
Feel the rhythm, save the universe. Enemies attack to an original jazz soundtrack — hand-drawn, hand-animated, and choreographed to the beat. It looks unlike anything else on your Steam library shelf.
A roguelite with thousands of ways to play. Die, keep your points, rebuild Matty differently every run. Three missions. Three unique space environments. Three bosses who will absolutely ruin your day the first time you meet them.
Science that actually sticks. Travel through the periodic table of elements as you progress. Every element unlocks new territory, new enemies, and real facts worth knowing. The only shooter where you finish smarter than you started.
