I was wondering if someone was going to make an ice platformer for this one! Despite all odds, you actually made it pretty fun. The ice didn't feel overly annoying because of the level design forcing the player to make lots of quick jumps. Really liked the visuals and music as well, got that Celeste vibe going on but in vector graphics form.
The sound effects are playing more in one ear depending on which side of the screen the character is on, which felt kind of odd. The exit image seems to be lower resolution than the other sprites.
The double jump took me a second to figure out because in other games I've played with double jump, the second jump gets you the same amount of speed as the first.
