It's working great now! My daughter finds this game very amusing (I wonder why)
Stuff I took notice of: the parallax background and all the character animations are very impressive! The player movement loop is pretty smooth and the simplistic poop animation works well in contrast. Also the fact that he has a sprite for both the jump up and fall down is nice and the death animation is great also (both the player and poops!)
The tranquil sounds of the forest with the occasional surprise fart is great :D The fact that his jumps goes through a seemingly random set of sounds is a nice touch.
I was going to give some feedback that the gameplay itself is pretty hard, but after giving it a couple of goes I've since figured the timing. Still, I think if the poops moved a tiny bit faster (so they would clear your jumps quicker) and being a bit more spaced out would help playability.
The image pops in a bit at the beginning of each round - perhaps using a stationary image (of each layer together) that gets loaded first, then loading the parallax layers over it and then deleting the stationary image when the user hits space to start would help hide this?
These are just suggestions to take with you for the future, this is a very impressive job and you should all be very proud of your work! Just 4 weeks of Java and you have A GAME!
Congrats to all!
