Development Build?
My game for the Mini-Ludum Dare is pretty much done now and I just uploaded it to itch.io. However, in the Unity 5 web player I’m getting “Development Build” scrawled along the bottom right of the screen despite this clearly being unchecked in the build settings.

Also, ticking it deliberately and re-exporting it increases the file size, which would suggest Unity knows this is unchecked but doesn’t much care. Some people are mentioning it on the Internets, but the solutions of delete your editor preferences or rebuild in release do not actually work for me. This is a shame because it makes everything look really low-rent.
The Windows build is fine, but I don’t want to just release a binary…

Any ideas?
But if you REALLY don’t want to make a windows build, I suggest porting onto the web as either a HTML or a Flash or some other means of exporting, since HTML5 seems to have the most support.
