I loved playing this game when I was younger! The movement was hard at first, but felt great once I got used to it. This is a pretty good version of it, but there are some things that I think hold it back:
-It's hard to tell if you are bigger than another fish (OG game solved this by making colored tiers)
-Fish spawning on the edge of the screen looks gimmicky. I would have them swim on from offscreen instead
