Very well made: Esthetics, sound, music, the whole feel of the game is really nice.
The game is a bit slow but I guess that's just part of the feel and you also didn't want to make it too difficult for newcomers I guess.
The tutorial, arrows, and everything you added made it very clear and obvious how it should be played and where to go and what to do, I think on this aspect you did an excellent job.
Just a small suggestion: a lot of the time it's not obvious what's in the foreground something the player can collide with and what's in the background just for esthetics. You can play a bit with the lighting or focus to make this a bit clearer.
Best game I've seen so far in this Game Jam. Well done!
