The Unity Engine supports Native Mac and Linux versions, Seems like a wasted opportunity to not have Executables for this title on those Two Operating Systems (Considering Steam hardly has any Games for the Mac) Also this should be done for Tea Time as that uses Unity too. I remember this game, really cool for being free...

game stays on black screen after the logos. nothing has fixed it

Performed by accident when I had two towers all the way to the very top and matched both of the top blocks at the exact same time. Blocks stopped falling until I bombed, but if I hadn't any bombs left, the game would have been softlocked for good. Maybe it doesn't register that the blocks had fallen because they didn't enter the play area?...

To get Gap professional you need to make only 3 gaps, not 100 as achievement description says. Same thing with Gap Expert - you need to make only 7 gaps, not 500. Counter for Gap guru seems to work like intended.
