i know exactly one person who owns a wii u, and i've been playing his roommate's copy of super mario maker on his wii u. i've made a few little concept sketches (including a remake of myfanwy ashmore's classic mario romhack, mario battle no. 1 - course id D71A-0000-001D-3CF4) but the one i put together today - bad plumbing - is the most developed one i've made so far.
everyone's trying to use mario maker to create the most difficult levels they can, but challenge doesn't really interest me. bad plumbing was an attempt to tell a little story, to focus on tone, texture and space. it's not unlike my 2008 mario romhack, mario goes underground.
you can check it out with this course id:
(it'll be listed as by "miguel," my wii u benefactor.) you need super mario maker to play it, but if someone posts a video, lemme know and i'll post it here! ENJOY.
