Hello! From what I've seen of this game, I'd like to give a review:
At first, it's promising. You meet a guy, you either make friends or just get an ending from walking away, you get along...
And then it starts to go downhill.
After it turns out he uses blood as red paint (how scary) it becomes a cookie-cutter yandere story. And that's my main problem with this game; it brings nothing new to the table. The worst part is the main character; for example, he licks one of his knives at one point. That didn't make me creeped out, it made me groan because it's too cliche.
Now, I'll cut you some slack; this is your first game, and we all have to start somewhere, so don't take this like I'm hating on you. I'm just tired of the same types of yandere stories that don't bring anything new.
I hope you continue making games in the future, however! :D
