I really like the colors and design for this! The game itself is cool, I think there’s an issue with the tracking mechanic for the enemy ships, because they would mostly just get in one big cluster when following me. I had a hard to seeing what difference the upgrades made, though after a few plays it made sense. I’m not sure if it was a bug or not, but on one of my plays I did a few upgrades, and then I couldn’t find any enemy ships! Everything was gone… started to feel a little creepy after a few minutes of searching.
Great job overall though!
