Clever use of the theme, but I think the rate in which ships spawn start too high. Also, I couple of times, the first ship spawned two ships on top of each other.
This i s my entry for Kenney Jam 2021.
The game was made over 48hours, the Theme for the jam was 'Rotation'.
The game is controlled by the mouse or touch, you must rotate the planets to get the various coloured rockets back to there home planets.
How high a score can you get.
