I'm not sure if this is intended, but afer hitting a Chaos Desert mage my additional bolts seem to stop working, as I can't select them.
pretty game breaking bug.
Not "bad", per se.
But there are a few key points you can work on

-background
-weapon powerups
3/5 for the effort and because it's your first game
