Hoping this game have more kinky routes later days. Except Math teacher there is no netori character left in the game either.
I could prefer swinger route starting different. Swinger couple could blackmail Nathan and Alice for to join their swing fun.
I think this game is great, but there's a bit of missed potential imho. For one thing, this could have been the scenario instead:
After you showed Vanessa what Martin was doing, some time passes and Martin gets a new girlfriend. The pair of them agree to swing with you and Mimi. (He already proved he wanted Mimi and Maria earlier. I don't see Maria swinging, but I definitely do see it from Mimi.)
Of course, doing the above prevents Alice from opening up to new experiences in the same way, so maybe this way is better (or even needed).
There are also many started and (effectively) abandoned plotlines with the teachers. I assume Walkius intends to return to these and take them further at some point, but for now there seems to be a lot of loose threads that were promising but have gone nowhere. The same can be said for Mirako and Abbigail, not to mention many of the younger girls Nate met outside of school: Tenma, Sharon, and Amy.
Under
normal circumstances (i.e., with most other games), I would be worried about completion of this game. Radio silence, lower quality, and rushing things are
not habits of Walkius, so I'm confident
most of these NPCs (if not all of them) will be addressed eventually. I liked having all of the school class events interspersed among main characters' progressions, and I honestly miss that quite a bit, since it broke up / limited the amount of "Skip to" or ⌛ button-clicking that was required to move to a sought-after event.
