I really enjoyed this, although I eventually had to quit because it was feeling like there was no difficulty ramp. Might be interesting to introduce health pick ups and only restore a smaller portion of health after each boss. Also maybe experiment with mouse aiming for the guns to counter some of the criticisms about the aiming. Really polished and looked great. Occasionally difficult to "read" my ship when explosions were happening in the distance but I have similar issues with a lot of colourful shmups.
