Well... it's a start. Once again, it's a game that should've been left to cook so you'd have enough content for players to know what you're doing beyond just being another generic college VN. I want to leave your game wanting more, not feeling like I need more just to see if you're doing something worth supporting. And using AI art, it's feasible that you could've had enough content in a reasonable timeframe.
It's not a demo, it's not early access, it's not even a proof of concept, it's purely proof that you can do a little bit of something in Ren'Py. With this being a sandbox game w/ repetitive content (classes) you should've brought at least the first 3 days of classes if not the first week. Just to be a proof of concept, you'd need to have integrated in your subsystems and show them functioning.
You have the regular suspects clapping and barking like seals, but the reality is there's not really enough here to provide feedback on. The only reason this game isn't immediately being buried in the back of my head is it's finally not another shitty ntr phone game that someone threw together over their lunch break.
