I love the idea of this
as a huge fan of simplistic game creation software and 8 Bit Dot Heroes but...
you're asking for trouble, man. Those are clearly Zelda assets that are slightly tweaked, and you even used to call it "Zelda Maker". Which, obviously, makes it sound like a Nintendo creation and having Mario Maker become a "Maker" series.
Think about this:
Mario Maker
Zelda Maker
Metroid Maker
Pokemon Maker
Anyways, got a bit sidetracked there for a second. Yes, this is lawsuit bait if I ever saw it, and because of that, I can't get excited for a game that I can't see surviving Nintendo pressure unless they really overhaul its marketing, sprites, and push it as its own thing.
