I'm not rating it a 1-star, because it is not awful and I don't hate it; I'm just ultimately unimpressed by it. The conversations don't really go anywhere, just the same kinds of flirtations with new AI images added, and the game isn't even finished, even though it is listed as such.
The music and setting are rather repetitive, the controls are pretty nonexistent, and there is nothing that really requires Unity over Ren'Py, even though Ren'Py would make this a lot easier to do things like change the settings and save, neither of which are available here in-game. This is pretty much a kinetic novel with dialogue choices that I'm not sure even do anything, and it is annoying to not be able to save or mute the music in-game.
Some interesting atmosphere and some nice pictures, but not really worth recommending nor playing again.
EDIT: Side note, there doesn't seem to be a way to quit in-game, so if you want to quit before the end, you are going to have to find a way to close it from outside the game. And if you do, and start up again, it seems to resume at an earlier point, but doesn't remove that text where you left off, so that can be confusing. I think you have to actually reset the game in the settings to start over; it is a bit peculiar.
