This was a decent start! I thought all the artwork was really cute, and the story drew me in. Plus, the story mode seems pretty ambitious for a jam game, considering there are all those places I'm assuming you'll go once the game gets updated. Plus, not only are you making sprites for the dress-up portion, but for all the character movements during the story mode too, I can't imagine it's easy piecing that all together. One thing that frustrated me though was seeing that this isn't playable on mobile; that felt strange considering all the input could be done with a mouse. The movement and jumping during the story mode seems like the exception, but (at least at this point, I don't know if it changes later in the story) it seems like you don't need to be making super precise movements, so on-screen arrows and a jump button seem like they would work.
Hope to see more of the game soon!
