Old School Genius
This does remind me of those games of old that were bleedin impossible, until you realised that the bosses routines could be avoided with the right timing.
It reminded me of old bosses of Sonic games, and also, Teenage Mutant Ninja Turtles, for the NES, most though. My desk used to have teeth marks because of those games :-P.
Just need to get the half health medal now! :D
