this concept is hilarious, haha. great thinking! i didn't manage to beat it yet, but i'll be back after i rate a few more games.
i really love the different abilities, and trying to analyze the levels to see what fish is best. that said, some of the fish are hard for me to find a use for and i usually stuck with the red one, too. the green fish in particular was a rough one for me--the hover seems like it could be useful, but i can't get the fish up over any obstacles so there's usually not much i can do with it. i'm wondering if the game just isn't running completely right on my computer, because i also noticed some weirdness with the charge jump (most fish seemed to jump lower than a regular jump even if i charged it to the same level of energy that a regular jump would take). but it could very easily be a skill issue too.
i also had trouble getting past some of my olf on the later levels. especially when i would use the orange fish--there would be a buncha bodies stuck to the walls, blocking me from getting places sometimes even after i switched to a different color fish. is there a way to clear the screen, or do i just need to be careful where i let them pile up?
