Hello to all,
I've just made some minor modifications on the demo a few minutes ago. It will get rid of some elements that might be a bit annoying, especially the ones regarding one of the 'virtual-world' stages after the tutorial.
Still, as far as it concerns, I've found none of the critical issues or bugs in the demo, so I believe you don't need to worry about them yet.
If there are any other problems that I do not seem to recognize yet, please let me know via comments and etc; I'll get to fix them as soon as possible.
Best,
ghilplip934.
