It's not bad but I could have just watched a playthrough because the "game" is so linear and the logic is so easy (even on "mean" difficulty) that there's no way to fail unless I was lobotomized.
It's a fun anime though. I should just watch the two seasons of the actual anime of it.
I think they do this on purpose, both Dangaronpa and Zero Escape had controversial endings to the series. I feel the V3 ending was a middle finger to the fans of the serie.
