The tutorial is a great addition to the game. I did understand the game this time, and got a score of 4200 on my second attempt. All the game information and feedback is in the form of audio, and I found I was actually doing better when I simply closed my eyes and focused on the sounds. I had some trouble understanding how the dodging worked. I mostly felt enemies to the left and right were easier to deal with. Is dodging actually required for these? What I felt was they miss anyway, since they either fire to the left or right of my ship, and then I line up and fire at them. Those straight on caused more trouble. Also got into trouble when there were multiple or overlapping bullets. Good job creating a pure audio game which is widely accessible!
