A free browser bullet heaven for your Shooting section. Steer a robot through a growing blob horde while its blaster fires automatically, collect crystals and choose one of three upgrade cards at each level-up: extra shots, orbiting orbs or a shock ring. Defeat the crowned boss to clear each short level. Works on desktop, phone and tablet with no account or download; levels and stars save in the browser. Developed by crokocat.
