I am using Scratch for my first Ludum Dare 49 hour game jam. Some people record their progress, I'll be uploading new versions as I go. There is nothing playable here yet and once there is I could end up dumping this anyway. We'll see how it goes in the next version update
I used Inkscape to make my circle and square, lol so detailed!! The theme for Ludum Dare 45 is "start with nothing"
