I have to say I usually avoid RPG Maker games but the hand-drawn art drew me to this one and I'm glad it did, this was fantastic! It's rare to see genuinely funny writing in a game but there are laughs throughout this one, and I loved the subversion of classic RPG tropes (it even kind of doubled back on itself with that ending and subverted expectations again!)
I thought the sanity system was slightly unnecessary (in fact I wanted to see the drawings of all the zombie villagers and taking sanity hits got in the way), but I understand why you included it from a game perspective. I also hit a bug a couple of times where an enemy would wander into the player character while they were inspecting something and then you'd take sanity hits over and over again until death. Thankfully I'd saved so it wasn't a massive issue.
Overall though, hats off. I can see the amount of work that went into this one, with the drawings and the amount of dialogue and the various collection quests etc. One of the best I've played.
