Game was cute!! Art was cute!! I like the magical school/academy idea and the feature of doing different things at night was clever in my opinion.
To be honest, I've never been a huge fan of Visual Novels because of my attention span, so I found it hard to keep my attention in one place for all of the dialogue, which was most of the game understandably, since it's a ren'py game. But I WANTED to pay attention because of the world being so interesting and so much going on.
I'm also probably not the target audience for this game because I'm not the biggest fan of NSFW type games *Usually. Not that this one was entirely NSFW or anything, or at the least I didn't encounter a scene that was explicitly explicit in my short time playing because I sorta had a feeling it would go sexual and I got a tad uncomfy with everyone seemingly wanting in my slime-person's pants. The constant crude nature of it left me feeling jarred tbh, but that's just me so nothing personal. But of course they live in a different world where I assume this is normal for them. This is just my personal opinion or feeling that I wanted to offer from a different perspective and not meant as a judgement in anyway!
BUT even beyond that, I was drawn in by the world building, so you did a good job!
There was a lot of creativity in the story and I can tell there was love put into the art and I loved the character's designs <3
All in all, positive ratings from me!!
I wish you luck in your future GameDev endeavors!!
