The art is amazing. I love the canyon effect you were able to pull off. I was able to beat it and oh man was it tough at the end. Re-spawning in the boss fight was a bit strange, sometimes the boss would show up and the fight would start again right away. Other times, I flew around for like 30 sec before it showed up. I really think that this game needs auto fire. My hand was starting to cramp from mashing space for so long, especially in the second phase of the boss. But overall I really liked it, great work.
