The concept is interesting, though the AI of the prof doesn't really fit the way you can play, as you can't move while you have the bullet and the time between waves of attack is really short the gameplay is pretty much waiting at some safe place the boss would randomly move to some place you can shoot at him then shoot and run while hoping for the best, took me four shots to get him the first two missed because he teleported i guess ? or did he had several hit points ?

Cool! I like bullet hells (:

I didn't beat the profesor though. :c
