SPOILER: Oh, I like this kind of story. It's a sweet revenge because that's what I'm gonna do if I ever been cheated www. Though personally I would rather kill the cheaters by myself first, then ask the demons to bring me to hell, only to kill them again in hell (maybe you can add that choice too, ofc no pressure ;)).
What I want to comment maybe the default setting for the sounds and musics. I was okay because I always set my device volume around 15%, but the music of this game really blasted off loudly the first time I opened it even though I use 10% volume in my laptop. And the scene where Alpha's spirit pacing right to left is too fast, I get dizzy just by looking at the screen.
Overall it's good story and who don't love sexy furry demons and girls~!
