A very polished-feeling experience with simple gameplay and amusing concepts. I would have enjoyed it more with a clearer light, though. I wandered around the whole first level several times with a YuyuNO in tow, and never did find the second cake.
I thought, "What if Youmu jumped from fear and was momentarily immobile each time a YuyuNO appeared?" That might strengthen the player's panic while also being in-character for our poor ghost-fearing half-dead gardener.
