So, the Jump'n'run is coming along quite well. I have changed the level layout just a little bit, removed two of the collectible "coins" but the basic game works, even though I only have 30 pixels available.

I have two vertically moving platforms, a collectible powerup that enables my character to shoot the enemy pixels which at the moment do nothing but block the way.

Just at the moment my character does not die if it falls off the screen. I will post a video lateron to show that the concept works. A picture just won't do it justice.
