Thanks for playing! No real end goal, other than to survive, as most endless runners go. Although I dabbled with the idea of a shop for ship upgrades, much like how you have in your game between waves! More health, faster speeds, maybe a cannon to shoot back, etc. Time did not permit it within the game jam, unfortunately.
Less contrast is a great idea, it would probably help to blur the lines. I’m a programmer by passion, trying to improve my art skills! Thank you for the suggestion.
