Very well done graphics, it is indeed a pleasure to control Guatemoc (it's also fun to wiggle its sprite while on the ladders :P )
The game is fun, even though I'm not the best player for puzzle platformers, I tend to love more action. It is a bit slow on restarting but that's not necessarily a bad thing, it gives more atmosphere.
I can feel the attention to detail you put in the game. Good job :D
