This was really cute! The robots are fun to line up for combos, and I like that this is an optional scoring mechanic and not fully necessary to progress. Final score: 57300, played on Windows 10 64-bit with keyboard.
My main issue with the game relates to object spawning: Power-ups can spawn on top of you and instantly take effect, and when the player dies and respawns, their semi-transparent sprite can blend in with any robots that happen to be passing by that spawnpoint.
