You have a good start for a game here. There are a few things I would work on. First the jump needs to be adjusted. You can keep jumping and leap all the way into the sky. Second I would try and put a note or something to tell the player they need to shoot the barrels. I spent a long time looking for the apples on the ground until I figured that out. With a little polish I think this will be a really good game. Keep up the good work!
