OK, so this is level 1 of a new series I'm making called Levels.
There are a bunch of different obstacles marbles need to avoid,
so let me explain.

WALLS - When a marble hits a wall, it will bounce in a diagonal
direction.

GOAL - Marbles need to hit the green box to win each level.

GATES - There are 2 different types of gates

WALL GATES - Wall gates have a gate opener and a wall. If a
marble touches a wall next to a gate opener, then the number on the
gate opener will go down. If it reaches 0 the corresponding gate will open.

HIT GATES - Hit gates lose health when a marble hits the gate so a squad of
more than one marble is good for taking those out.
