Ricochet (itch) (Percival_designs)

Ricochet is a bullet hell game where your only weapon is a disk which you must throw around the room to defeat a slew of alienified ex-crew members, who have taken over your ship. Battle your way through each room killing all enemies before taking the warp pad to the next room, again and again, until you get to your only means of escape, the interplanetary warp pad.
