This game is unnerving as hell. Maybe it's the shopkeeper's appearance or maybe it's all the dark/horror Tamagotchi parodies I've played. But I would not be surprised if this game had some dark hidden lore you could uncover from secret dialogue or something. The shopkeeper is designed like a true fae (the ones that like to kidnap and fuck with people) as well rather than those fairy tale fairies that look more human like. Though I suppose the base premise is kinda fucked as it is, you befriend them, then profit off training and selling these "tamago" like slaves.
