Didnt know a single thing about this game before i picked it up, it is a very short and sweet story that i will not spoil here.

Depending on your actions the story changes and there are alot of things to miss depending on how you play but you can replay it quickly since the game is that short it may take about an hour or even less to finish your first playtrough and then to go trough the rest of the game for different endings is super fast aswell so if you want to see all aspects of it then it wont take much time at all,

Id say give it a go if have some time to relax and you like a nice story to boot.
