It’s definitely an acquired taste and I can 100% understand why people dislike this game.

Particularly the japanese version is 5/5 and deserves it for everything (design, music, whole plot with 5 branches for missions, characters, artstyle), no doubt, surely influenced by things like Ghost in the Shell and Serial Experiments Lain. It deserves more recognition than it has.
Don't play the western one, it's "not the one".
