Develop a particular branch of this game into a RPG with a storyline and characters as cubes.

So the storyline I can think of now is:

You are a cube (pick name w/o numbers or symbols, and color)

You are in school

You like another cube, but the cube likes someone else

they get together and u get angry, first few missions is sabotage daily life of the other cube's xxxfriend

then it evolves into all out war
