The game is good, with one glaring issue. The movement. It doesn't really feel right. Issue 1.) Your momentum gets completely killed after a jump. Isuue 2.) You start by barely moving. Issue 3.) You take really long to get to top speed. Did you use kinematic body, or no body on your player, because if you did, you should've used rigidbody 2d instead for a game jam. If you revamp movement, and polish out everything else, you have a really great, commercially viable game, for a cheap, like $2, price tag on itch.io. If you did want to release this on steam, it is more work, but it is possible. Keep working on this!
