Well done, I'll never take my second stick for granted again! Great use of an economical art style. Very easy to understand and fun to play. I started playing with keyboard but I had to get my controller out. Snappier rotation (I think you have too much smoothing) and/or spread on the bullet bursts could help with aiming. The enemies tend to clump up a bit which is cool, but I think some more interesting AI behaviours could deepen the strategy.
