Concussive Maintenance

USE PORTALS

Use your portals to teleport. You can put a portal on any white surface, with a twist: you only get one portal. Instead of walking through portals to teleport, this one works a bit differently...

SLAM INTO WALLS

Teleportation is activated by changing your momentum. What does that mean? If you want to teleport, you need to slam into something. Jump off a ledge, fly into the roof, or run into a wall full speed to activate portals. Hit something hard enough and you'll be teleported through your portal.

MAINTAIN YOUR MOMENTUM

You keep your momentum when you teleport. However fast you're moving before you teleport is how fast you fly out of the portal, but what about the next one? Shoot a new portal mid-air to keep your momentum even longer. Chain portals together like this to finish the level.

PUZZLE FEATURES

Each puzzle will have different components. Buttons that open doors, blocks to hold down buttons, flying platforms, pools filled with toxic bacteria, and more! Each puzzle will require a combination of features to complete. Figure out how they all fit together and finish the puzzles as quickly as possible.
