TL;DR
Love all the routes. Art is great. Would love more of the Sister bonding route. Interested in where the NTR route goes or if it branches. Love the multiple POV changes.

I noticed a timeline discrepancy where in the sister route Akemi notices Ota had a screen name with Mio in it and Akemi knows Mio exists and refuses to go out with Ota because Akemi knows Ota is just trying to use her to get to Mio. But in the NTR/NTS route she hooks up with him anyway with the same username. The story staying the same is probably more important, but I'd love if there was an attempt or explanation by Ota to use a different screen name to hook up with Akemi in that route.

Going into this game I figured it would be like a lot of the other NTS based content. But I gotta say I was pleasantly surprised. Any of the NTS content early on is only suggested/hinted at around half is just imagination by the MC. He questions how much he enjoys it and what about it scares him and excites him. It is only after all this that the Player is given the choice on what to do. I think the solid setup to the backstory for the different routes is top notch; genuinely. It reads and feels like the mind of an uncertain person experiencing a new idea/experience and confronting it honestly, for the most part.

I feel like the sister route is the most standard that isn't just absolute vanilla, which I think still has its place. To get to it, all you have to do is be open to change, but not be an actual weirdo. It's that simple. All this talk about the NTR route being crushing is crazy because you have to be psychotic to accidentally get to it. There are so many off ramps to get off the crazy train. I think like 5-6 separate identical boxes you have to check off in a row to get there. I'm here to experience everything even it isn't my cup of tea so I had my fun and am actually looking forward to where it will go and maybe a splitting of the NTR path where it might go into mutual sharing or stealing or whatever. At least a bit of introspection on all parties after the extended roller coaster they've been on for at this point like 7-8 months.

One of my favorite parts is the fact that the POV of the story shifts around to solidify the time line and really get a good perspective on the emotions of everyone in the situation, drawing out the tension and really elevating the final reveal.
