I love the simple gameplay, though, I just want to let you know it doesn't satisfy the game jam rules :(
What I mean is the "float" moving. Moving between pixels basically.
You could try fixing that by introducing a fixed 84*48 grid! Good luck!
It shouldn’t have any float or subpixel movement in the game. All movements are done at a minimum of 1 pixel at a time.
It’s the main reason I couldn’t add parallax scrolling for a starry background. They move the same speed as the ship, 1 pixel per update, so it just got too fast and chaotic.
Happy to share the source if people need to see it.
