Good luck!
Once you know how many graphics you need, you can can choose a style that makes it possible to draw them before the deadline.
Yeah, I think I’ll stay simple.
I spent the last few days testing various styles and searching a palette on the internet.
I’ve settled to a resolution of 40 * 12 px. I first tried the smallest resolution suggested by the rules, 80 * 24, but it was too many pixels for me so I divided the dimensions by two! :p
