Hey! Was great to check out your game last Saturday. I'll definitely let you know when the next test build for OTS is out - maybe in a couple of weeks or so.
I found a link to the dithering article I mentioned: https://forums.tigsource.com/index.php?topic=40832.msg1363742#msg1363742 not sure if it'll be useful for your current project but I think it's worth reading regardless!
