itch.io

I've ran into this problem a few times and it has kept me from playing some of the top games like this one. i have a windows with the itch.io browser downloaded but says the game is "available on a non-compatible third party site", what are my next steps and how do I go about playing?

ive been using autowin in the war (i know i know) im trying to save kana and got to the screen with three dice. how do i advance?

my game keeps crashing when i have to visit Rachel in her dormroom and i cannot progress in her story
