A simple errand takes a turn for the surreal when our hero, forced away from the video game console and out of the house, stumbles down a hole into the middle of the earth where he is, of course, tasked with tracking down magical gems. The same thing happened to me the other day. A little bit retro, mixed with a healthy dose of metroidvania and high-difficulty platforming, and Kodachrome is a weird but appealing little challenge.
