Shuichi is a very compelling protagonist on his own, and the way he hates solving crimes repeatedly being used against him and seeing him overcome that is moving.
i suck at platformers, so i cant comment on the gameplay but celeste sticks with me for how well it's gameplay meshes well with what it wants to say and it isn't too heavy either, big fan
I don't like saying pieces of fiction changed my life, but SeaBed definitely informed my perception of grief. I'm completely in love with this VN and there's nothing like it. Also has the relationship that ripped my heart out the most.
