I enjoyed the beginning, I'm generally a fan of the sort of 'best friend dynamic' and I thought it was fun and well written, so that's kind of a given for me. It also felt like a lot of effort was put into everything, I enjoyed seeing the story progress. The quality I felt went down a little bit once we went to the past, and really went down a lot once we were back in the present and onwards.
For those portions, I really only played through them because I was committed and wanted to see everything. Even if I could think of how I could like certain ideas, it was really hard for me to buy how sex was suddenly everywhere, and that kept being in the back of my mind.
On that topic, I should mention, the game starts off very slowly, no sexual content for a long time, with big focus on the plot. Later on, this seems to flip. It creates a weird situation where if you enjoy the early parts, you may be disappointed by how different it becomes. On the other hand, if you're looking for sex scenes, you'll have to sit through a large amount of content with virtually nothing of the sort.
There are very few exclusive options to pick, none are significant, and none are dialogue choices, so you have no influence on the MC's behavior at all. The sandbox aspect of the game is not badly implemented, there's no grinding and it's clearly marked where you should go.
A rating of two stars felt too low, four felt too high, so I'm giving it a three. A high end three, the game isn't bad, but it could be better, and it's very inconsistent.
