I usually enjoy visual novels where the protagonist has some kind of time travel powers, because it gives a whole new metanarrative dimension to the game, and this one is not a exeption. I think is pretty cool that the games encourages you to rewind and try different options on people.
I loved the game from the start and the plotwist and surrealist scenes of the last chapter, but I hated the fact that all your past choices don't matter when you get to choose one of the two endings. Until that part of the game, all your small and big choices have some meaning, even if it's just a different voiceline or alternative route to something, so I wasn't expecting to make a that kind of decission at the end of the game.
Apart from that, a really good visual novel. Excellent story, writing and characters, but sadly devoid of multiple endings like others.
