Fun gameplay, enjoyed finding the secrets. Good pickup design in that stuff only dropped health or item charge if you had need for it, and otherwise gave points.
Wish it had music, but otherwise was pretty solid.
If I can add a slight critique with the level design, it'd be in the very last enemy stage before the boss. The point where you drop down with fireballs shooting in both directions has a bit of geometry that goes inwards at the bottom for no particular reason. I thought it might be hinting at a more subtle secret room, but I just fell to my death lol. The actual secret areas are well hinted at, but you might want to just make that a straight line down like the rest of the platforms to avoid curious folks like me plummeting to their doom xP
Game was quite enjoyable, the character art was very cute, gameplay was well balanced, nice work!
