Awesome! Nice use of wall jumping. One glitch I encountered is on level 2 (the one with the sunset where you start with three gunmen on your right), if you go all the way to the right and wall-jump off the top wall, the game freezes, then goes all the way to the bottom and you die. Also, you might want to reset the score after you die, at least to what it was at the beginning of the level (example - I start level X with 50 points, I get 20 points then die, I should restart the level with 50 points).
