This version works on my Mac! However I am noticing bugs that I think are not intentional haha. From the third level and on gravity does not have an effect on me and I will start very slowly floating upward triggered by either touching the platform or random other actions. Sometimes I can win a level still and other times I float too quickly to hit the folder. Once I got in the folder but continued floating and it never triggered a win level event haha (level 6. Didn't get past this one because of this). Perhaps this is something to do with getting it to work on a Mac that messed wit some settings? Dunno! But what I did play of the game I enjoyed!
