Awesome stuff. Rare a game gets me to think outside of my norms. Maybe a replay button for when you complete the game so you can get back into it? Keep it up!
Awesome game and I enjoy the concept, that's rare nowadays. Hope to see some additions in the future. But this bug is annoying: Hanger #4 does nothing once you purchase 4x speed speed upgrades: You only have 3 ships (so upgrading the 4th does nothing). Keep up the good work dev.
