Quite the satisfying rage game you've made here. I've never really played one of these kinds of games before so I'm not quite great at it, but I played for about two hours and I really like the subtle effects, like the particles, the squashing and stretching of the player, the shifting of the pitch of the sound effects depending on your speed. It all comes together in such a nice way that just feels very satisfying to control.
Anyway this is about as far as I'm going in this game. No idea how much of the game is left, but what I played was pretty nice.
The only thing is, the climbing animation has a weird thing going on with seeing parts of the sprite sheet you're probably not supposed to see.
Everything else is really great, though! I really enjoy this game
