Such an amazing game— if you are on the edge about whether to play it or not, all I can say is: DO IT! The extended demo is several hours of enrapturing fun and it's entirely FREE! I did not expect to fall in love with the characters to the extent that I did, but in love I fell none-the-less haha. I can't say it enough, the game is really that good. The music, the art, the writing, the lovable LIs— this one is a work of art.
Go on— give it a try!
