Funny but I think there are a few bugs; you cannot eat some fishes even when they are much smaller than you, thats why I automatical die at the moment when I pick up the "size"-upgrade, I made myself undefeatable with a cheat and got 3times bigger than the screen, but I dont finish the game(?), can I even finish the game or what?
Nice game with a good concept, but the "bugs" really ruin it
