If you're into the HD series this is a great game to pick up.
Despite a few negative reviews I picked this game up for my collection.
So far I really enjoy the game, it looks good, it's funny, the game play is minimal but fun.
It's more of a visual novel then the classic RPG style game were accustomed to in the HD series.
Despite a lot of negative feed back and let's players saying it's a bad game (mainly due to people probaly not understanding how to play the game from skipping tutorials most likely) it's really a hidden gem.
It's a game you'll either love or hate and I'm my opinion this game is a breath of fresh air, I really like it (7 hours playtime)
It's not a game like Hatsune Miku project diva or OSU it's more of a visual novel and raising simulator combination.
I'd personally give this game a 9.5/10 defintly worth the buy; you'd need to really play it for yourself to know if you'll like it or not YouTube videos do this no justice
