Mario Maker is possible on PTC. Some of the PTC Wikis games/apps are similar, in a way:
Platform Editor (Alpha), created by Xeyler
^^^^^^ Level Editor
Onward! Level Editor
and some more, too.
So if anyone could make Mario Maker PTC, i'd be happy to have the game on-the-go, too! (I might make it myself, if I had the tools :P )
