I started this challenge and it's pretty fun.

• First round: Program a runner to jump over hurdles
• Second round: Program runners to jump over hurdles. Problem here is that 4 games are running at the same time, and you can only give 1 input every game-loop that'll go to all 4 games
• Third round: 4 different games are being played at the same time, and you have to give an input that'll be for all 4 of them every game-loop

They have this graphical interface that'll actually show what your character is doing, which makes it more interesting than just a "code-only" leetcode or adventofcode challenge
