This is a bit of a tough one to judge.
On one hand, this is some excellent art. The drawings, the animations, the teasing, it all comes together masterfully. A gallery system is included to let the player experience it all again any time, which is a fantastic touch that many RPGMaker games miss out on (though I feel like more and more are starting to include it).
In addition, the side characters break up any monotony, and there's a variety of body types and personalities to choose from, even some on the fantasy side (faeries, the lady from RE7, a santa girl, etc.)
On the other hand, this is an almost textbook example of how RPGMaker can almost bring an entire project down by itself. Nearly every bad RPGM design choice is on display here;
-Huge maps with nothing in them + hard to remember layouts (the school especially is a nightmare)
-Convoluted systems that add almost nothing to gameplay (literal hourly events that are easy to miss? A farming system with seemingly no point?)
-Long, long progression for events (some girls require more than 120 affection to reach later events!)
-Bugs and other issues dragging down the player.
-Long, unskippable transitions/animations with no way to speed them up.
I don't think the dev is intentionally doing a lot of this, many of these things are almost intrinsic to RPGM. Thankfully, the dev also included cheats for people like me, who have no patience for this kind of grind, but even those sometimes don't work. (Unlocking scenes in the gallery can be especially frustrating.)
To summarize: Great art, good characters and dialog, horrible player experience. Play it if you have a ton of time to kill (and some serious tolerance for RPGM gameplay.) Otherwise, download it for the gallery or art that comes with the game.
