Do some colours decay over time?

I think this is a sweet idea. I liked your suggestion of having the particle decay into two particles that have a repeating pattern of movement (They decay, then move, then recombine, then decay, etc.). Gives us the chance to make a challenge for the player in waiting for the decay, then observing only one of the particles, then combining that particle with another as-of-yet uninvolved particle.

IDEA FOR LATER: One level starts with only one monstrous atomic entity, composed of 8 particles. Player observes particle until it decays into two entities of 4 particles. Player observes one until it decays into two entities of two particles. The final decay presents the player with the particle needed to win the level.

Alright so I think this establishes that Red Blue and Yellow are 'atomic' in that they are indivisible, while all other combos decay over some variable amount of time.

Yeah, the primary colors. It's a nice visual cue as to what the particles are.
