Is it like an absolute need for the story to feel complete / ended, or is it just for people who really like the other 2 girls? I heard things like Kasumi(?)'s route is the "true ending", so do I need to buy it for the full story?

the player count numbers are kinda low and idk if its worth buying

It happens on both of them, when i run the game, the software runs and there's audio but it's just black screen and i noticed that there is no option ribbons (like File,Config and Help) at the top of the software. But when i dock the handheld device at a monitor, it shows the visuals and the option ribbons shows perfectly fine. i tried googling and asking Discord and no one has any solutions at all. It seems like it's only this game that i have this issue on, any other VN works perfectly fine....

Anyone tried running it on Steam Deck? How is it?

So yeah, I've completed all the routes and all the Other Stories for that matter, tried launching Dies irae ~Acta est fabula~ with region set in japanese and still there's no way for it to work, here's a screenshot if it helps. http://es.tinypic.com/view.php?pic=b8whsk&s=9#.Wjb9_FXiaUk...
