TRI A First-Person Puzzle Exploration Game

TRI is a first-person puzzle exploration adventure game where you place corner points onto walls to build walkable triangular platforms. Find a way through the towers and dungeons in sophisticated levels.

Solve puzzles, climb vertiginous abysses, reflect light-rays and try not to lose your mind when you‘re falling upside-down. Don‘t worry - the TRIs will let you create your own paths in this magical world.

The game is currently in alpha and can be pre-ordered on Humble Store (which gets you a desura key too), Desura and is looking for votes on Steam's greenlight.
