I made so many updates since this itch version (the trailer and screenshots on this page represent that of the itch version of the game, not the latest version that's available on other platforms).
I have since added a reincarnation mechanic, balanced difficulty, improved the interface, added power ups... The game is currently rated 9.3 (1.1k votes) on Crazy Games! And I'm still updating it just about daily.
I will leave this free version here. For the latest version, also free, see https://www.crazygames.com/game/liquid-swarm.
A Steam version is also coming up: Liquid Swarm on Steam
