If you do get back in to mario a 3d one would be cool.

Chances are I will make a 3D Mario fan-game eventually. I'm just not sure when since I can't animate 3D models yet. And Polly 3 will come out in a few months most likely. It's going quite well. :P The only way to play Ultra Cube Land is by downloading it, however you'd be wasting your time since it's super short and pretty bad.
