These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
But seriously, even though there is a giant overtone about rocks and crystals, a lot of the comic's designs are pretty trippy, and sometimes the adventure's art kind of looks like something out of a drug trip, the author has said otherwise about where he gets his ideas.
Crowning Music of Awesome: The first run of Crystal Rave did have some music, but none that was really memorable. Mineral Caper starts with an 8-bit like starting screen (Which was retroactively added to the story no less) and also starts Chapter 1 with a haunting refrain of wind and chimes. It is all pretty glorious.
