Scary evil is scary. ...and EVIL!
Gameplay-wise Aya is a mess. You can't read the instructions, but that's not a huge loss here. You're going to walk around with a lantern, barely able to see anything, looking for keys to doors. You also have to dodge the monsters whom you can't lure away, sneak past, or destroy. Every cut scene is long, unskippable, and adds little to the experience. The textures, music, and cut scenes will all become too familiar since there's no variety, either.
...but really, the travesty here is the premise of the game. "Scary evil is scary and scaring you to death! It's so evil it scared all of the scary demons, too!* (*um, except the ones in the mazes. Those are SCARIER...) So now you have to escape, um, your own soul (13 times, to be exact) by avoiding the SCARIER demons and waiting until they move out of your way on their own so you can find the keys that allow you to escape what the description calls "inescapable" nightmares. (Er, your soul. ...or maybe Satan's curse. These descriptions seem interchangeable in the description.)
If the story seems absurd, the gameplay won't be any better for you. I suggest you pass on both.
