Thanks everyone for the feedback!
@alex457 @scowsh @ben-taylor Alright, I've gotten a chance to test on a Mac and I've uploaded a new app file which should work (it worked for me at least).
@baylej That's odd. What computer do you have? If it's super old it might not be able to handle some of the graphics APIs being used.
@frogman Damn, never seen that one before. Thanks for reporting it.
@vibromatic Glad you enjoyed it. A good suggestion. I made it vibrate when you're low and get hit, but probably not enough emphasis on it ticking away.
