Hey!
I always liked game where you managed different chars/powers (Kid chameleon, The lost vikings, crusader of centy, etc) so you get a big thumbs up for that! :) First sign breaking the 4th wall? more thumbs up! :D i did miss some bad guys to shot on so i hopping you can add them in future iterations of the game.. I got soft stuck on the screen with the 3 moving boulders and 2 rows of spikes.. got there with only the waterboy (yeah im calling him/she/it that! :D) so i couldnt go back or pass the spikes. Keep up the good work!
Code related: after bing hit by a moving bolder on top you can sit on it like an elevator! fun stuff! ^^ if you double jump right after stepping on spikes you can pass walls.
