Catching your head after bouncing it off of an enemy feels REALLY good. And using it as a your health reminds me of playing Sonic and scrambling to recollect your rings. Great work!

This is a well-polished little platformer. I really like the sprites and animations. Using the skull as both 'health' and a weapon is an interesting mechanic. The ability to catch your skull for increased damage adds a lot of potential for skilled players. The sound effects and music are also nice and fit the theme perfectly. My only feedback—though this might just be a skill issue on my part—is that the game feels quite hard and unforgiving. The checkpoint helped, but I still found it very difficult to progress.
