I really likes the books and feathers! They instantly made me feel like there was some challenge to the game.
The art style was great for a jam.
The first level wasn't super fun for needing 300 coins. Felt like dying didn't matter. So maybe another mechanic is needed there or just less coins.
Bugs: for the library after beating it if you click the play button to do the level again, you don't get your money. You have to click the home button to get paid.
