Can anyone recomend more VN dating sim games like this one

Title.

I see people talking about a secret ending after seeing every girl route. I can't get it, nor I can find it searching on internet. So it's a joke or it's real?

Estou fazendo a tradução para ptbr, quando eu acabar eu atualizo aqui o link do github.

Spoiler warning, obviously. The preview when you mouse-over the thread doesn't respect spoiler tags, and still shows spoilers, so don't do that either if you like not being spoiled. Really liking the game so far, I don't play Visual Novels much but this is pretty nice. A wild ride from beginning to end, and it really was something where there's more than meets the eye. As to the endings themselves, I got the ending where I: Trusted Kat instead of killing her, and chose Yui before I blacked out...
