Did you try to click the button? I made the text black (chanced that now) it can also be that the lightmaps where not completly baked or that it was not 64bits. when the jam is over i would love you to check it out when i upload the hopefully fixed version... I really would like some feedback!
really, also not on mac. Why the hell did i stay up to 06.00 in de morning to finish the jam if no one can play it :P
A F* FOUND OUT THE PROBLEM. I added a text last minute with a tip and forgot to turn-off the raycast so if you click, you click on text that does nothing only being in the way....
