First of all - thanks for the great game! I've been looking for something like this for a long time and I think I finally found it.
Unfortunately, I found out that you dropped OSX support after I made a purchase, and you did a lot of improvements in the last version, to the level I'd say 0.12 is a different game.
I know you probably been asked this question many times before, but is there any chance of releasing 0.12 for OSX? Since 0.10 is already a cross-platform, I'd guess it shouldn't be that big of a problem to make an OSX build. I know you don't have Mac anymore, but maybe you can borrow it for some time from some of your friends? (:
There aren't that many good games for Mac and I hope you'll find a way to continue OSX version development, as well as adding more features.
