Played it an Newgrounds, and like I said from there: "Great idea for a low budget, music class...".
The actual gaming was way easier than the tutorial in my honesty. I think that's because, it's like what you've learned from school that doesn't go that well in the real world (am I right? :D ). It was a great experience playing around with stuff at your chair while in class, while I don't look the professor's lecture. Pure slice of life lol! Great work :D
