I can't even make something this good in a week!
With just 1 hour there's not much room for planning haha. I was a bit stuck with the idea and I decided to make a platformer and place a grid in the background (because grid was the theme). Then I was thinking about how cool it'd be to edit the level, but I wasn't sure about how to implement that. Then I switched to another idea where you had to fill the whole grid with color as fast as possible, which wasn't super fun. And then it was like "wait, what if I combine these two".
Just throwing stuff at the engine and going for whatever feels good is a nice way to prototype small new mechanics.
