For me, it was a good game and especially had a lot of good moments. It just felt like each route was too short plus some of the endings felt pretty samey (the netorare endings especially plus they were pretty short). I think each girl should have had half the routes and simply flesh out the leftover routes. Like each girl has one route with the main guy and 1 or 2 routes with other characters. Each route just feels like its over too fast and by the end, not much really happens. Another alternative would be to leave the rest of the routes alone and flesh out all three heroine's routes with the main netori dude. For the main netori dude, he simply doesn't have enough scenes. When he finally banged one of the girls and the ending came right after I was pretty disappointed since the game was going strong until it ended abruptly.
The actual scenes were pretty great, especially when you know the heroines are with someone and you can barely peep on them. Really liked the sounds in those scenes plus the fact that you can go back to where you peeped on them the next day to see the aftermath of what happened. I'm looking forward to another game made by this dev. I just hope its a bit more focused and doesn't end when things get good.
The mystery parts were great, I loved that mc was unaware of what was going on, it was all left to the imagination of the player, who could watch what's going on in the memory events if they chose so. The use of moans/sex sounds and white stuff remaining the day after was good too.
But it needed a little something more to be amazing, like for example showing stats changing for even the girl in the mayor's house, and maybe add a flavor dialogue the day after. Also that's what I meant by more events in the village, I wanted the netori dude to basically ntr train every woman in the village (prob needs more characters in it for that though), and then showing the stats changing over time. I mean, there is the girl in the inn, with a random sex scene, but it felt like the dev just stopped in the middle of something here, it felt unfinished.
On the routes I completely agree, they were way too short for the corruption part and scattered among too many endings, but it makes sense since the story was short overall. I didn't play the hypnosis village part, it was less interesting than the netori dude seducing them.
Also, yes, each girl deserved a bigger corruption route, and I'm really hoping that the next game from the dev gets better. Mystery ntr rpg game devs are rare, and good ones even rarer.
