I really like the idea of being a collectible coin rescuing their kind :)! The jump feels pretty nice, though the fast camera movement involved in it made me a little dizzy. There wasn't much challenge involved, as the hero was unfortunately really difficult to come by: I could camp in the brick room all day waiting for coins to pop up if I wanted. A faster strategy would obviously be to keep collecting the ridiculous amount of money in the out-of-bounds section, but that's the kind of secret that renders the rest of the game meaningless once you know about it :(.

If you plan on adding a leaderboard after the jam, I suggest balancing the way to gain score first, as well as adding a timer or a real threat for a more interesting challenge. Nonetheless, wish you good luck in the future and congrats on the entry :)!
