Maybe try uploading a downloadable version. In my game there are some bugs that only happen outside the editor too so I get how frustrating it can be.
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.
Hell yeah, I’ll give it a go after work, you should play/rate/comment on other people’s games so that they come back here and know to rate yours!
