Wow, this is great so far. I love the general plot idea and the 'staying in character' twist! Totally reminds me of an otome game I once played on my PSVita, sadly I can't remember the name right now :/ Definitely getting some Saw and Danganronpa vibes, too :D
It's to soon to tell, if I'll like the characters or not, but I'm very interested in getting to know them further. The Artwork for them in their profiles is great though. And A. seems to be a sweethart :3 I'm here to befriend and save them all (and maybe romance them too ;))
I'm looking forward to see where this is going. Keep up the good work! :) And please have fun in the process :3
