The plot itself, while promising, is a tad bit short. In my first playthrough, I was shocked to find myself dead just by choosing to hide with Hiroki. I made no other decisions other than hiding with him, which led me to thinking there was a glitch in the dialouge. I restarted the game, and the same thing happened. Eventually, I realized it was the same for every character I clicked on.
I'm still wondering if this is what is supposed to happen... Is there perhaps a walkthrough?
Anyways, the game was fairly interesting, and the character's conversations with each other are quite natural... I'm looking forward to any of your future works! :)
