This is probably my best (finished) project ever. If I could somehow get the original X-Ball, and X-Ball 2, I would. Here are descriptions of the other two:
X-Ball- Made this around 2009, and it is very similar to this, except no scripting in density platforms. You can also float, in this one there are levels and the typing is trying to prevent to win, not to help you.
X-Ball 2- This actually got deleted. Anyways, instead of on a flat plane, you get to explore planets in the solar sytem. This is great fun.
I would love longish game ideas!!!
Also, you should try playing orbellum infinity, it is really great!
