@KermM: Thank you very much!

I do agree though. I had expected it to be much harder to put all of the intended features in. And indeed, before the first post here, I had done the core of the game (the graphics, the dropping animations, pair finding/removing, no moves checking(!)) which was really hard and needed a lot of thought and pseudo code, but after that the rest was relatively easy. I also found that it got easier the further along I came in terms of creating the code necessary for my needs. It's been a fun challenge!
EDIT: Also, the bug seems to be completely gone now!

EDIT2: My screen blanked in ACTION mode on level 5 and my RAM got cleared. That's nice, because the AppVar is in RAM during the game, so all progress was deleted... Again, I hope this is just my calc, otherwise I wouldn't know what to do. Something must be toying with me here...
I've uploaded the latest and probably the last beta version of the game featuring an AppVar for data saving. I've also changed it into an Ion program, so the icon is gone, but that wasn't that fancy to begin with...
Look out for the full version, I'll probably post that at the end of the weekend.
