Short Circuit

Short Circuit is the 3rd level of RoboTraps, taking place in the main generator room of the factory. It features a sequential level layout, in which robots have to be guided past hazards one after another, and introduces switches.

Level Design
The level has the robots walk past the obstacles individually. First, Alice walks a unique path to the left. Then, Bob goes to the right. And finally, Clark and Dennis also go right. As the robots walk down the paths, they will step on switches, toggling the deadly electrical fences on and off. To solve the level, the player needs to understand how switches work, and to reroute the robots' paths accordingly using the two Switchable Arrows so they will not walk into an electric fence.

Notable elements in the visual design are multiple giant cogs and a malfunctioning fuse box.

New game mechanics

 * Switches
 * Switchable Walls

Solution
The main challenge here is anticipating which way the robots will pick and altering the Switchable Arrows so that the robots will go the save path out of two. For Alice, this is the right path, for Bob, it's the left. It also is the left for Clark and Dennis, as they will both step on the same Switch, making the Electricity go left and then right again. Use the blue lever in the middle of the platform once to make Alice go right, then use it once more after she did and wait for the other robots to reach the goal. Things will get more complicated once any of the robots is destroyed, so make sure to get it right from the start or alter your strategy once it happens.

Trivia

 * Switches already appear in both previous levels, but are not explained there, yet, as understanding them is not necessary to beating them.
 * This level is unique in that the robots have to be guided past hazards one after another, but without the player controlling when they start. Instead, a grey robot walking outside the main stage will trigger switches to release them at certain times.
 * This is one of only two levels in which less than five robots can be saved, with the other being level 9, Silent Green.
 * It is also one of only two levels to feature multiple exits, with the other being level 1, Learning-By-Dying.
