Silent Green

Silent Green is the 9th level of RoboTraps, taking place in the sewers. It features only Alice and Bob and spreads out game elements in too far for the player to see all at once. It also is the first level of the Crash Complex.

Level Design
The level has the office capsule stop in the middle of the sewer tube, with Bob walking on a ledge to the left and Alice walking on the right. Two levers must be used in a way that allows both robots to reach the exit. However, as the player can't see both Bob's and Alice's path at the same time, they will need to plan their steps carefully lest one of the two will be killed.

To go with the sewer theme, several barrels full with nuclear waste are seen lying around.

New game mechanics
The level introduces breaking blocks, although they have no effect on the actual gameplay, yet.

Solution
First of all, use the blue lever once to let Bob go past the Switchable Arrow and switch it back once he went past it to keep Alice from getting buzz sawed. After that, wait until Bob gets stuck on the next blue arrow. You won't be able to change it directly, as that'll kill Alice, who stands on top of the blue saw now, and letting Alice go past the purple Saw first will impose a time limit on you, as when you do, she will walk up to a red Switch that, as soon as she steps on it, makes the goal unreachable for Bob due to a saw popping up. Therefore, you must first activate the purple lever, then quickly activate the blue one, and then the purple one again. If you are fast enough, Bob should be able to walk past the red saw before Alice reaches the Switch.

Trivia

 * The level name is a pun on the dystopian movie Soilent Green.
