Awesome work. I loved the atmosphere you created. The gameplay was clever and intuitive. I hope you continue developing this out, it was really pleasant.
I thought it was fun! I had the same challenge - I didn't realize I was shooting straight down at first, but once I figured it out I definitely enjoyed blowing up the pirate ships.
I really enjoyed this. The music and the color scheme made for a whimsical atmosphere and the gameplay was the right amount of challenging to get me to want to keep trying until I completed it. Great work!
