I- w-wow, honestly, I didn't expect myself to shed tears today but here we are (But I got to finish writing the comment so I'll pull through!).
Such a beautiful bittersweet work, I love the dialog of the game especially Kronii being the warden of time. The genre of mini-games also feels fitting for each of the members too, Sana with this bubbly Space shoot em up (well its more like orbit em up, in a way huh), Fauna with the chill calm fishing game and Mumei with high energy of DOOM shooter!
My only comment is probably at MOOM section, the camera seems turns to a sharp 180 at certain points (Maybe I was playing on the web version?)
But still, wonderful work and writings especially at the end! Will cry again! Council/Promise Forever!
