Hi.
These are my impressions after playing the version at the time of this post, which I'm guessing it's the first upload at itch.io.
Overall, it's a light introduction. Nora's admission in "finding it easy to chat with the MC" is a bit weird, since they just met and what little dialogue they had just then wasn't anything potentially cringe-worthy. No full blown confessions either, so maybe it would make more sense for a few more chats at different times, or even a Nora-then either Mina or Alex-and again Nora, something to demonstrate that the MC is earning her trust. Food for thought.
Also, at the bar, first Mina seems reluctant but strangely turned on with the MC's permission to flirt with guys to network. And right then she's getting all cozy and cute with a random dude and going into the restroom with him? True, she's buzzed (or more) but still seems a bit weird, maybe even going too fast? Will that be a possible ending, go too fast with sharing Mina and get burned, so to speak? (please don't answear if you don't want to post spoilers! lol)
As for Alex, if the MC gets "closer" to her, I wonder if Mina will be willing to share, or if that's an only path for cheating. I'm not going back to try again, but I'm curious if it will be possible for threesomes with MC and Mina and Alex, or make Mina a "cuck", lol.
Then there's the possibility of maybe sharing Mina with the MC's best friend/group of friends. Posting pictures on a social web with or without Mina's knowledge, perhaps? What about asking Mina to help the MC getting a promotion by going on "illicit" dates with his boss?
These are just ideas I've had after playing, don't mind the mumbling...
Anyway, following, I'm very curious how you're planning to develop this project. I hope you'll enjoy the process and make something you're proud of!
Cheers!
