“Plankton is the kind of game that makes you question every decision that led you to this point in life. It starts off all cute and relaxing, and then Level 12 arrives like a tiny microscopic war crime. I have never worked so hard to feed something that doesn’t even know I exist.…”

“Level 12 was extremely tedious but for a 1 dollar game you can't complain really. Fun art style.”
