Amazing story that leaves me craving more after the end

I’ll be honest and say I thought it was going to be a boring game at first, but I later became hooked onto the story after the plot twists started occurring, and couldn’t put my phone down until the end. Like what the other reviewers said, I loved everything about the game, and the mood and setting was converted very well through the visuals. The moral statements from the game are very strong, too, and it even touches on real-life issues like mental illnesses. I’ve played Tasokare Hotel before this, and I must say I enjoyed this game as much as the other one.

!!!!Spoilers below!!!!!

However, I was disappointed that it was never explained who the mysterious man selling weird wares and making claims about the destruction on 1st Sep was, or more about him (what his purpose was, etc) and his background. I really wish there would be a sequel as I became really attached to the characters, but I know there won’t be one since the game has already tied up all loose ends. I would love it if they made an alternate ending leading to a sequel or something, though!

I got this game just out of boredom one night and didn't really expect anything amazing out of it, but this is easily one of the best point and click mystery games I've ever played. The art and music are gorgeous, the characters are all very unique, the story is very intriguing, the puzzles are actually challenging, and there are quite a few routes. I've yet to find another point and click novel type phone game that has multiple routes determined by what items you collect. It's done so well that it really honestly makes you want to go back and try to find all of the routes and character cards. The game immediately makes you feel connected to the characters and has you truly feel sad for them or celebrate with them. The fact that this game is free is completely ridiculous to me; they could easily sell this. Please play it, it's truly amazing in every sense of the word.

Hey what the heck I didn’t expect perfection from a awful download screen but that’s what I got, almost all male cast for like, a couple dozen chapters. Which is amazing, no annoying anime girls.. not one!! I would’ve loved some more brainwashed solider boys but Yknow this is fine. [spoiler]’s suicide was stunning, like actually, I was playing it at lunch and I had to have my friend click next I knew it was coming and I was petrified. It’s like danganronpa and ddlc all over again! I never knew I would like historical fiction Japanese politics games but I really hope I can find something like this with more politics in the future, but for now I think this little app I would’ve never found regularly is one of my top 5 fav visual novels. If I have to pay money later on to unlock stuff.. I’m going broke is all I’m saying..
