To use portals effectively, place your blue portal near yourself and your orange portal at the destination you want to reach. Remember that momentum carries through portals, so if you fall from a height into a floor portal, you'll launch out of a wall portal at high speed. Mastering this momentum trick is key to solving many of the harder chambers.

Use WASD to move, the mouse to look around, and Space to jump. Left click shoots a blue portal and right click shoots an orange portal. Press E to interact with objects like buttons and cubes.
