I guess the first thing to get out of the way is that it's a game premised on incremental progress. There's a snowballing effect that each run becomes clearly easier than the previous. It creates the feeling of progress.
The game is based on a repeating period of time. Wake up on your first day of college, get a number of days, then it ends and you go back to the beginning. Each time you face it the player has a little more awareness as well as being able to retain more and more of your stats.
First run was me trying to figure out what I was supposed to be doing and failing miserably. Second run had me hook up with a girl. A few later and I'd done everything the game had to offer.
The game will presumably get balanced over time as more content gets added, but I'd put a mild warning that some players will inevitably call it grindy. Which it kind of is. But it's all with a purpose, and most of what isn't character interaction is kept down to a button click or two.
The game also makes a point of using lesser-known girls, which is always a positive to me. Only half a dozen girls with sex scenes for now, but a couple of candidates are in the game and, again, I presume this will be developed further. Something that gives me confidence in projects is when from the start you can see all the core concepts and mechanics are there. The stats make sense and are easy to follow. Improving them is simple enough. Progress with girls is typically easy to find (the only one I got confused by is mentioned in the game's hints with the prompt to start her off). Basically, the dev only needs to flesh out the world from here and, aside from a lack of an ending, it already feels mostly "complete". It'd definitely be short as a finished article, but it could pass for one. Even then there's hours of content if you're a completionist.
I found one small bug (an interaction led to a dead end if you failed a check, but nothing a couple of click of the back button and then waiting a little longer couldn't fix), and there's one achievement that I think is missable (may be intended, doesn't really affect gameplay). Otherwise pretty much flawless in my view. I'm sure there are some but I'm not sure I even noticed any spelling errors, which is rare indeed for a pedant like me.
