It's solid, especially for a free/first project. A lot of clear inspiration from mystic messenger, which isn't a bad thing - they clearly put some thought into what worked and what made sense to incorporate into this game. Routes were concise, which I like, although none of them particularly resonated with me - the flirting style was not really to my taste and it was very similar route-to-route. Characters had their charming moments, just needs some refinement, and a little more differentiation between them.

The core concept framing the narrative was interesting and genuinely unexpected, and I'd encourage the writers to keep making projects like this - with a little more experience under their belts I think they could pull off something really great.
