With what little I knew, and especially getting to the last part, I expected to go down hating Monika all the way. But then the game turned around by corrupting Sayori, and Monika ends up bailing everyone out. It actually made me feel bad.
I hate that they game makes me feel so helpless when all this bad stuff started to happen. And I wish I could have done more. But knowing the creators of these kinds of things, evoking those feelings was probably intended.
