If you don't have a home key, you can activate it anyway by pressing fn + a key with an arrow pointing to the left but not the "normal" left key. Saw it on Wikipedia, after toddling a bit with my keyboard, was able to pass level 31 :)
I like this game, but I have an issue with the saving system. When I leave the game and come back then next day or whatever, I've always got to start back 1, 2, or 3 chambers back from where I was.. Think you can fix this ?
The 29th isn't that bad, you just gotta get the hang of it.. Passing the middle is the hardest thing to really get right, but after 100 deaths, it gets easier, I reckon :)
