Going to bed (3 am in California).

Have input and basic collisions working. In the scene below, the two blue/green things are Meshes. The one one the left is controlled by keyboard input while the one on the left is a stand-in for an enemy and just stands there. If either Mesh collides with a Free Pixel (or, in the case of the motionless NPC, the Free Pixels collide with the it), the Mesh will regenerate one piece (they’re both plus signs for now). If the player Mesh collides with an NPC mesh, the colliding blocks get shot off in a random direction–turning red for a few frames to connote that they just exploded (and can’t be re-absorbed right away).

Next up: Mesh Editor (for the player to add pixels), input dampening (when on a small board, don’t move so damn fast), and some basic AIs to be bad guys.
