Sorry! A friend of mine had trouble on his high-end mac too, before I published. Is the frame rate chunky? I can't recreate it, as my windows box always runs it fine, and a couple crappy old macbooks I have access to always run it fine too. Are you perhaps on a super hi-res retina display and the game defaulted to like 4K or something? Try turning down the res in the dialog before the game starts...?
Hey, thanks for that, I will give it a go. My Mac is not a super high end one but the frame rate wasn't the best and the cursor was a real pain because the game cursor did not match the Mac's so it would open all the other apps as I played on. Still your game is sweet, hope to finish it one day. Thank YOU!
