I saw your short on YouTube about this and decided to try it out. endearing little project that must've been fun to make! Mouthing out the sounds is something I've not seen in the jam yet so that's very creative haha
I do want to notice you that if you use the slam down ability onto an upwards spring, you just straight up get softlocked cuz you never actually touch the ground when going up and down on a spring, so you just can't move.
Other than that, I don't think both normal and air dash should take up the same 'dash slot' since you're using a limited resource dedicated towards a specific ability. It feels unintentionally punishing.
Overall very fun game though =)
