was this game inspired by the "jumper" series? It sure looked like it. Anyway, I like the overall idea of "meatboy". The visual presentation was light, but the animation was very good. Nice job on those little slideshows at the beginning of each chapter, those were quite interesting. The gameplay and controls were very simple. G'job. I also liked the blood splattering all over the place and tainting the tiles. It was a nice touch. Fun levels, overall pretty balanced. Really good idea, that 3/5 level completion thing.
Now for the complaints. My main complaint is the touchyness of the character. Maybe add more friction to terrain, or reduce maximum speed? Very often, I'd jump onto a platform, then as I chained a jump to the next one, fell into salt or whatever was there. I'd also like to complain about the sawblades. The main problem with those is they reach a little bit out of their allowed space, which makes them deadlier than they'd normally be. The cannons fire a bit too quickly, and it'd be cool to be able to jump on their cannon balls.
Overall a very good game. Pretty hard, too. Nice job, guys.
