very flawed
the good: fun short game with different weapons, boss and medals
the bad: clunky controls with inverted mouse makes it awkward to shoot and try to avoid fireballs at the same time; Fireballs do not have to actually touch you to damage you, slow reloading time and inability to switch weapons while reloading, inability to switch weapons in the first few seconds of play, seems impossible to get the "10 dead on delivery" medal, and the adds are twice as loud as the game sounds, so as a tip it's not good to play this with headphones, it hurts your ears.
