Thanks for the feedback, especially pertaining to the mac! If you have an XBOX 360 controller that you can plug in to the Mac, it should work, but I don't know how Mac treats those kind of controllers. I use to have a Mac, if I still did I would test my games on them as well to make sure they were okay.
Enemies definitely could be a pain, I just got too use to them and their patterns over the weekend and didn't have any testers before uploading, so I will have to agree that at least slowing them down would have been good and possibly adjusting their jumping.
