This is my current project:
It's a community where you can build your own game in the editor and share it online--complete with physics and Lua scripting!I posted
a game similar to this several months ago, but that one didn't work out--some of the code was written over a year ago, when I didn't really know what I was doing.
So after distracting myself with some other projects for a while, I decided to start over from scratch a few months ago. I've already added quite a lot of features, but there's still work to be done--namely, online multiplayer.
You can try it yourself here
