Following a further series of convoluted and increasingly implausible adventures – the likes of which are far too exciting to describe here – Alice and Bob have escaped the zombie apocalypse and must now negotiate the following maze. They need to get from the red arrow on the left to the red arrow on the right, leaving each black dot via an edge of the same colour as the one they entered it by. They can only switch from one colour to another if indicated halfway along an edge. Most of the edges can be traversed in either direction, but those marked with an arrow are one-way only. Can you help Alice and Bob escape before they evaporate under the weight of their own continuity?
