Is that what it is? Thanks, I saw the error code, but I had no idea what it was. I looked it up and couldn't find anything, either. Wasn't sure what part of it I was supposed to look at.
Well, the input is half the problem. On both builds (downloadable and web), sprites disappear. I'll upload the desktop version so you can see what I mean.
Edit: The sprites disappearing glitch is fixed! The downloadable version works.
