Ok, here's my experience with the game. It's long, really fucking long. But generally well written with some good humor here and there (looking at you, Makina). Some of the girls are pretty exaggerated in their personalities, and the MC is kinda bland but not annoyingly so. I got some H scenes with Amane around midway through. 4 or 5 well written ones, but nothing after the jungle thing started. The replay gallery shows at least two scenes with each girl, but I got none of this, and since there are literally only 4 places along the plot where you are given a choice, it shouldn't be too hard to replay. I don't see how those choices are going to move me onto the other girls, but hey, they might. Does anyone have tips about that? Is the game different if I restart it, newgame+ style?
To sum it up, I liked it, but tbh it's way longer than it needs to be.
