By far my most popular sketch, this was a great task to practice implementing OOP in the form of game objects. The game isetlf was inspired by Capture the Flag done in Scratch by ThisIsADumbName.
I have struggled a lot in designing it so that the map scales properly for different window sizes. The current implementation works by assuming a certain scale (the monitor I built it on: 1920x919), and then scaling everything from that to whatever size window it runs in.
