So for about a week now all my friends have said Osu! is not a game but is a scratch project, Microsoft word project, software and even a TXT document, So i have come here to ask the community, Please dont just say its a rythm based game because i know that is what it is but all my friends are even saying guitar hero isnt a game and that its a training client for guitar, So i would like a in depth answer of what Osu! is
