I enjoyed the game play concept, always been a platform junkie. Using your dead bodies as safe passage was a nice twist as well.
However the jumping sound effect got really grating to my ears, and seeing how its a platformer you do jump quite a bit.
As for the meta aspect, Maryo wrestling control from you was a nice touch, but sometimes those sections felt like they lasted a tiny bit too long. Maybe allowing the player to advance his text would be a good way to adjust that. That would take alittle meta out of it though...
Overall Nice Job!
