A retro metroidvania platformer by MNWS, The Ruins of Machi Itcza will have you feeling like Pitfall Harry. The purely exploration gameplay is tempered a bit by slow character movement, but overall, the game captures the archaeological feel of rediscovering something ancient and mysterious.
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.
