Mario Maker has had some mixed reviews and varied opinions said about it since release. While most of what's available to play is absolute garbage, like all content creation games, you have to dig a little deep to find the occasional diamond in the rough.
Super Mario vs. Mecha Bowzilla is one such diamond! Just check out all the work that goes into fighting this monstrosity! With clever design you pretty much have to use all the tricks any good Mario game has taught you over the years just to take this thing's knees out.
