Originally released as an entry for the 2010 Ridiculous Games Contest. It's basically a Pokémon-type game, but with monsters based on all sorts of OHRRPGCE-related things... random enemies, heroes, villains, and even forum users. Since the original release I've expanded it further beyond the length of the first demo, and as of December 2016 it's probably safe to call the game roughly two-thirds finished.
December 23rd UPDATE: For the first time since 2010, a new version has been uploaded! New to this version are an updated palette (not the default OHR greens as seen in the screenshot), rebalanced Accuracy and Evade stats (I'd recommend starting with a new save file because of that), two more towns, two gyms to go with those towns, several new dungeon-type areas, and around 40 catchable monsters out of the 55 total. (See the "Puckamon_History.txt" file included with the game for more changes.)
