Nice entry! lot to like, I found the hit boxes a little evil, for instance the morph ball you could end up getting "spiked" where you really didn't think you were going to...
But It's such an ambitious undertaking to produce a game so big for a jam and the fact you managed to get this quantity of game while keeping pretty high quality is great! I think there are some rough edges to iron out yet - but with a little more polish you have a great game I would happily pay for!
