// Cloned by Vaidas Buzas on 5 Dec 2022 from World "Catch the flag" by Meabh Horan
// Please leave this clone trail here.
//Cloned Mark Humphrys Complex world.
//Also took parts from Mark Humphrys Model world for my two characters.
/* AIM:
Try and find the most flags before the red enemy catches you.
It gets more difficult as you go on.
Use the arrow keys to move: Up, Down, Left, Right.
Also sneaky jump forward with space bar but this is meant to be like a cheat code.
Recommend user to adjust camera so they can view the grid depending on their preference.
