You welcome man! In fact the changes on refund can solve all this problems, we too had a concern if the game would have problems running on different systems, and we thought that it would help to have the demo so people would not give us bad reviews. Do not think like that, bad reviews come to you even if you have the demo :lol:
Thanks for the compliments on The Rabbit Hole, it is a hard game (at least some of the puzzles), but we enjoyed creating it. We are about to release Apocalypse Rider, if you want to try it soon just send me a message ;).
