nice for your first game
this is really cool for your first game.. the graphics are really nice, also the game is fun to play. but there's definitely room for improvement. like when I'm going down from a hill, it's just like I'm falling, the collusion detection isn't good there. Also when i hit the knives nothing happens (or when I'm jumping i got onto them). And it wasn't really clear that I had jump on a stone, after that jump on a tack of a tree, and then jump onto the building. And the game doesn't really have a plot (except for searching a taco XD).But it's still all good for your first game. in the next game you might add enemy's and attacks, lives, and make it more an platform game. But overall: really good job !
