I find it hard to believe that this was even a game jam entry that was made in a week - it feels so complete and polished! The sprites, animations, and overall aesthetics are fantastic and charming. The game was simple to understand and fun to play, and the tutorial was excellently done (you guys even had a "skip tutorial" option!). The music is really nice, and the sound design is excellent as well. Great job to everyone involved!
The only feedback I really have is that the movement can be made to be a little quicker and smoother - however this is a really minor nitpick in relation to the rest of the game, however I mention it should you guys revisit this game in the future to expand upon it.
(Don't mean to brag, but my record is 2496m across ~5 tries.)
