After finishing all of the non-good end routes since I can't find it, I can say that this game suffers from the same problem a lot of copycat game suffer from. They're lazy. They aren't trying to be better than the game they're copying. They're just using the theme without any of the soul. Take this game for example. Scars of Summer allows you to mix and match routes allowing you to see Ryoka in the overworld at various locations with various guys having hidden sex. This game has next to no overworld sex. There's no point in playing the game "fair". The best thing to do is save and sleep for multiple days, check the journal to see what days have the events and then reload your save and sleep until those days. It's insanely boring. Why is the map so big if we can't do anything on it? Scars of Summer has overworld sex on practically every map. This game feels unfinished. The main routes are fine but on the days without an event, there is nothing to do.
Another problem is the game is so copy and paste. No matter what route you're on or what just happened, she never reacts to it. She has the same generic lines all the time. During the homeless man route she see's his dick while he's sleep and runs away in a panic. I found her at the park right after and she just has her generic drinking water line. No thoughts about what happened or anything. The overworld version of her doesn't change outside of predetermined times in each route. But even then she just has the same changes in each route. She becomes indifferent to your character, locks her door so you can't interact with her and starts ignoring you. With the exact same dialog in every route. It's lazy. Her changes should be unique for every route. She should wear different clothes per route. It's boring. Even her mom only has the same generic lines all game despite the things her daughter does. In fact, she's having noisy sex in the next room with the teacher and her mom is like, "durr, they're studying!". Her mom is a huge missed opportunity. She could easily have tons of dialog about the changes in her daughter on a per route basis. She should have her own story like the sister in Scars of Summer. The rest of the homeless camp don't' have anything to do. Let them have her.
Overall, if this game was a first try It'd be alright but it took an established formula and did nothing with it. No innovation and far less effort was put into it. It does nothing better than Scars of Summer and even shamelessly copies it on several points. Like the shota letting his two friends fool around with her and the homeless guy having silhouetted tent sex. I will say that this game has better routes than "My girlfriend, me and fireworks." But that game is dark as hell if you get the good end which gives it points. 2 of the 3 routes end up sucking really bad though.
