Thanks, and sorry about the bug you ended up hitting when you tested the game. :\
If you import the sample game again and the bug is still there, let me know.
I'll try to look into your data structures issues soon. I'm away from my primary computer right now, so I'm going to be waiting a few days before I get a ram upgrade and can do any real work. Sorry for the delay on this!
Also, Irock said good work on the video.
