Added a new scene, fixed most of the bugs I could find and made Kaly's fight just a tiny bit more challenging. You can get version 1.0.1 at:

I don't know if the scene freeze bug was fixed because it didn't produce an error message on my machine, so the changes I made probably solved it but I'm not 100% certain. I did, however, play like a thousand runs and it didn't happen again, so I'm very optimistic about it.
(Edit) Ok, so the scene freeze bug was not actually fixed and I went back trying to solve it. Hopefully it's working now!
Take care! :)
