Looking at this project, games created by rcbasicfans and the source code of those games, it really looks really promising. Syntax looks a lot like in BlitzBasic/BlitzMax. Project is actively developed. I really need to look at this project a little bit closer and try to use it for one of my next projects.
Thanks for checking this project out. I have been developing this since early 2015. I am currently working on a action platformer with it myself which I am hoping to release a demo for soon. Someone recommended I put it on itch so more people could discover it. Please check out the forum at rcbasic.freeforums.net
