Not quite. It is tagged as having NSFW content, so one expects NSFW content. It isn't clear what the (April Fools) in the title refers to. Some part of the game is a joke, but it still has NSFW content, otherwise the tagging would be plain out wrong. I doubt that everyone will deduce that the NSFW content is about an aged-up version of the loli, so it is fair enough to point it out so that people won't waste their time on something they might not enjoy as much in the end.
