Go into A Jump Too Far, go forward and take a left to the eye. Stare down the wall, then proceed 
through Running Into Trouble by walking on the bridge, as the entity in the middle of this room gets
excited with movement, and will disintegrate the bridge. Then in The Ground Floor, collect the two 
blue blocks. Backtrack to the beginning, at the door labeled "The End", then utilize the red gun's 
block-multiplying and mass-painting properties to paint from the floor up a wall to meet with the 
other red blocks. The game will then take you into the finale, which mostly involves transferring 
blocks in various areas.
