Wanted to try it out since your description was promising a lot and I also enjoy music focused games but I was unable to play. When the game finishes downloading, the executable is not automatically found by the installer so you have to manually launch the game from the install folder. Once I had gotten it working, the menu was rather confusing since I didn't know I could shoot the blocks. Also, the new game doesn't seem to work, it just goes to a loading screen and then returns to the main menu.
Hope you keep developing the game so I can see what you were going for.
