As other have mentioned it was not clear that we had to click either on the rhythm line or the enemy to shoot them but once that was understood then it was easy to get going. I was hoping that the speed-up mechanic was controlled by how many enemies I took down making the difficulty level be controlled by how skilled I am. (Perhaps this is something that can happen later.) Sadly, the game broke after I died the first time, which appear to put me where I died, and then the music stopped and did not loop, and the speed up counter stopped at 5 and then took 30 seconds to get to 0. :P lol Other than that, the music was fun to listen to and the simplicity of the game play makes it easy to get understand and play
