While Super Mario Maker was released to largely stellar reviews, some minor complaints were noted — specifically, lack of features normally found in a typical Mario game like checkpoints and the ability to package levels together as “Worlds.” While the latter still hasn’t been resolved, user RagnarokX has managed to develop a full-on checkpoint system with the tools given — the video below from Kotaku shows how it works.
Essentially, after clearing a large potion of the level, players will come across a text password. Then, players can input that password through a series of music boxes, allowing access to a warp pipe (as seen below).
But what exactly is happening behind the scenes? The below picture illustrates the contraption and how the off-screen elements function into the mechanism:
For players who want to try out this level, the code is: 1B6D-0000-00A3-FD76!
