Behind the old manor stands a glasshouse full of sleepy plants, and every night at midnight a wall of ghostly glass appears across its middle. Nobody can see the panes, but the plants can feel them blocking the moonlight. The friendly ghosts who live there call the mystery Phantom Panes, and they have asked pixel Markiplier to roll in on a brass flower cart and clear the glass with a glowing wisp.
The panes only flash into sight when the wisp strikes one, and they glow faintly when it drifts close, so every hit is a clue. Old lanterns sometimes float down from the broken glass, worth catching on the cart. Each cleared wall is followed by a new one that comes in faster. Let the wisp slip past the cart three times and the night is over. How many walls can pixel Markiplier find before dawn?
