Today, I play a Puzzle Map called A Light in the Dark, made by Mirgeaux. It's tests your parkour skills in the dark as you only have the light to help to get passed the levels.

Follow the light to escape the darkness...

In this original map the main goal is to complete each stage of levels. Every stage takes place in the 'darkness'. Walk, run, and jump across the pathways of light to reach the end. The light can be hard to see sometimes...you just have to search for it...
