This game is so awesome and professionally constructed (no pun intended)! I'm loving the art style and the skits. Great job. I didn't really find anything wrong with the jumping, but the character did get stuck in a crate once. Couldn't do anything but restart.
This game reminds me of that TI calculator game, Block Dude. They share the basic concept, but Block Dude is more of a puzzler. Maybe I'll try to remake that in Construct...
Well, anyway, good work with the game!
