City of the Damned 2 - Apocalypse.
There's some line of blue and red squares with an arrow at the start and end indicating the direction i'm supposed to travel in. I've tried walking along it, jumping on only the blue squares, jumping on only the red squares, waiting until the sirens sound before doing it but nothing ever happens. If I find out this is some unfinished part of the map, I will cook some comfort food and get fat.
