I really like your music and sounds. How the player actually puts an effort into that jump is awesome(sound wise). The slippery floor is a bit hard until you get used to it. As a developer myself I love the developer related comments and the mini game during load time(next time maybe a dino jump game?).
I didn't like that at launch I saw a sign up screen. I believe it is for a leaderboard of sort, but having to confirm an email for a jam game almost made me quit. So maybe work on your onboarding experience.
