I like this game!
It's very simple but really fun. It's a pretty unique take on the jam.
I like the bird sprites, they're cute. Getting the skins is a pretty good motivator. Though I'd make them more expensive because I was able to get the rainbow one pretty easily.
But edit the jam submission info.
The limitation is "cant stop moving". The theme is birds.
So under "use of limitation" change it to something like 'fish can't stop moving'.
