That's an impressive game ! You made everything in only 2 days ?! Seriously, that's awesome !
It was such a good idea to use note sequences this way, and your power-ups are interesting. The level design was clear and easy to understand, good job!
I had to read your comment in order to understand what to do in the first place, and it was kind of complex to reproduce each melody for the first time, but then, I had great fun !
Also, such an inventive interpretation for that theme !
Congratulations !
