+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
