XD Great minds think alike? I think the themes really lend themselves to a space ship/drill and asteroid approach, plus the time limit of a game jam and the 2 Color theme REALLY encourages a 2D arcade style game.
I definitely recommend experimenting with adding some quick juice to your game, and maybe making some reusable tools/classes that you can implement quickly in future games. You're welcome to use entirely or borrow parts of my CameraShaker, and anything else in my MykaelosUnityLibrary for that matter.
Thanks for the feedback and thanks for playing!
