The platforming was pretty solid! I was surprised there was no coins out of reach of any other issue of the type, and I didn't feel like the hitboxes (although punishing in their own way) were too unfair.
I'm not sure this was specifically a good submission for this game jam. I would have liked to get a little more context as to the setting or coins (Maybe an incentive to collect them?), but it's solid work nonetheless!
Good job!
