Thanks a lot for the feedback! At the beginning I planned to introduce a couple more locations (as mentioned in the description, the Castle and Graveyards packs were something I was considering), but of course I did not have the time. As for sounds, that's kind of my main weak spot (both sound design and music), and I left it at the very end, where, of course, I ran out of time.
Sorry for that bug, some friends of mine noticed it as well, but it was after the time ran out; for some reason the signals connecting the buttons cleared all the variables they were supposed to pass. Used to work, but that was the very first component I developed, and apparently it broke partway through...
