Man... Should I still play Catherine, guys? I think I know the twist.Catherine is a demon/succubus, right?
Is there more to it/still worth going through?
Can I just watch it on YT?
God yes, it's a great game. Knowing the twist doesn't take away any of the fun.
You can watch it on YT, but a lot of the enjoyment comes from playing it yourself and seeing what ending you get.
