Thank you for the in depth review! I agree that it could be optimized a bit more but I just was not sure if it was the game or my computer. I also agree that it could be a bit harder. I don't know why you had a problem with the sound effects because the game does have some sound effects for shooting and power ups. The music is set to loop so that is either a bug or a problem with the engine. I would love to rate your game but I can't really download games. Otherwise, great review and thank you! I will definitely take care of some points you mentioned in the future.
