P3TT

P3TT is a single-player, first-person puzzle game in which you wake up trapped in a remote facility and work your way through a series of levels to escape. To open each level’s doors and reach the exit, you examine your surroundings and figure out the actions you need to take.

Portals and time

You use blue and orange portals alongside time-manipulation abilities. Objects and laser beams can pass through different wormholes, letting you combine physics and time manipulation to solve puzzles.

Growing challenges

The challenges build on what you have already encountered, while introducing new controls as you progress. The game’s fundamentals resemble those of Valve’s Portal games.
