I think you could make a good game out of this. Though I think the up arrow key should be jump and the space key should be fire. Plus you should be able to hold down the key to fire. Do that and make like 20 more levels and it will be fun.
another glitch... the guy some hoe got stuck in midair. i tried to get him in the truck but his foot was like pinned to the air. i pulled him into the truck and he sprang back.
