This game is absolutely beautiful in it's visuals, probably one of the prettiest I've seen in the jam. The music fits perfectly and all of the little sound effects, like jumping on platforms is perfect as well. I wish it was longer and had a better conclusion to the story, but for 1 week, that's entirely understandable! I hope you keep working on this and turn it into a full game, I'd happily play it again!
The only improvement I could suggest would be to make the platforming a little more fluid through something like coyote time.
Great game overall!
