Crescent Pale Mist
A 2.5D Action Platformer with RPG elements developed by ClassiC-Shikoukairo and released in March of 2006. Gameplay is varied and unique, with mazelike multi-linear stages, an impressive variety of enemies, and bullet-hell-esque boss battles.
Crescent has been licensed for western publication by Rockin’ Android. Please support them when it’s officially released (TN: they’re still kind of obscure so they need all the help they can get).
I’m still, however, hosting the translated Item Locations Guide if finding them is as confusing as it seems it was meant to be.
