It works. The simplicity of it makes it even more impressive. Seeing a curious being enter your room telling you a story, however simple, hooked me. The game only sometimes concludes those stories, which makes me wonder even the inconsequential people, will this come back to bite me? It's like a simple quest system, but better because i don't know if the story will have a nice conclusion like there is in your typical rpg, the uncertainty is inticing. Cute graphics and chill music work well with the simple gameplay. 

One gripe, the gameplay encourages us to detect the personal prejudices of the creator so we can get better rewards from the dialogues. It's a great way to shove your prejudices down someone's throat, but the more disagreement the person has with your "correct judgements" the more they might dislike the game.
