Its a fine byte-sized platformer, I think there is potential from their mechanics, it was fun to improvize air combos given the mobility you get by punching in the air and having an additional jump.
On that same note I did have some issues with the attack moves: since the punch also works as a 'forward dash', it leaves you really exposed to enemies/hazards (especially if they come from above, and also agains the 1st boss where it just keeps running towards you) it left me hoping for more variety of attacks, like an upwards/downwards hit.
