Maxwell's goal is to collect Starites, which are found by solving various puzzles and helping people out with his magical notepad.
hydrideGS in this movie gives a demonstration on how such a game with so many possibilities wasn't playtested as thoroughly by crashing it multiple times. Many of these crashes come from glitches that are simple to perform and are very possible to do accidentally.
There is author's commentary in the YouTube and downloadable encodes in the form of soft subtitles.
