Great. Something about the way this is set up feels like a joke; like the ending is the "punchline," even though it's just as absurd and nonsensical as the setup.
I love the character design (my personal favorite is the little dude that just says "It should of been me"); I love the simplicity; I love the humor. I have no negatives that wouldn't just be nitpicking or pointing out the obvious. Amazing little experience.
(Should a fish with legs increase or decrease the fishiness score? On one hand, it is literally, physically more fish. On the other hand, it is less of a fish, as fish don't typically have legs. I am conflicted.)
