This world is a simulation.
Marbles (40 marbles with 2 of each color displayed)
enter the arena filled with boxes.
Each hit to a box gives 1 pt to its value.
A marble can steal a box by simply hitting it.
At the end of a timer, the marbles are despawned and
the scores are totaled and displayed at the left.

Mess around with the timer and run the simulation many times
and see the results!
I'll make some updates in the future, enjoy for now!
