I don't understand how this guy is morbidly obese when he has to go through so much trouble to get his breakfast every day, not to mention the workout he gets from all that jumping and running just to get through his daily routine, god must have cursed him with the slowest metabolism of all time.
Just set up a couple fully upgraded, non comboed tazers right at the beginning, and then further away a Nuke combo (Red fires first, +blue +blue) so that when the wave of monsters are clustered by the tazers they get the shit nuked out of them. ;) This is especially helpful for the later levels.
Pretty good game all and all, bosses could use a bit less health, specifically the 2nd one, and i found the control system a bit clunky, but other than that, amazing, 4/5
