Kuon is an interesting, complicated #PS2 #SurvivalHorrorGame. The story feels a bit well trodden, someone unleashing an evil on a place to achieve a nefarious goal, but with a feudal Japanese themeing. My vagueness here is deliberate, as there would be too much to talk about.
There are two playable characters with going through the events of the game, but with noticeable differences. Equipped with a Melee weapon and magical cards to cast spells to fend off ghosts and some other monsters.
What makes this game complicated is the lack of understanding where you need to go. Especially during the first part of the game. Progression is locked behind easy to overlook documents, which you may have bypassed as you knew where you needed to go.
If you play a lot of classic Resident Evil style games, you'll probably be in your element here. It's not a bad game, with enough intrigue to make you wonder what the Heck is going on.
