Hmm, I'll need to check to see about having it do about a better "wall check" for dropping items, it shouldn't allow you to drop them in the wall. One thing I noticed (I built this on a Mac, and developed on a Mac, and only got a chance to check it recently on windows) is that the transitions between screens on Windows takes too long, which probably affected this lamp issue. I'll try and fix that so it won't happen again.
The music issue is one I've known about, and have been trying to fix for awhile...
Glad you enjoyed it so much! Thank you for letting me know about the problems.
