Hello hello!
A friend and I have been working on a prototype for a platformer where you control multiple characters in several dimensions simultaneously. Attached is a video. (You can find the source code here: https://github.com/Mulan-Szechuan-Sauce/hugheverett3).
Any thoughts on the idea? Let me know if you want to play (but not compile) it yourself and I'll upload the compiled binaries.
Of course, ignore the terrible artwork 
EDIT: Attached an example of some 3 and 4 pane levels. I didn't win them in case you want to try yourself!
