In "Tri" you get the Tri Force Field Generator Gun, which allows you to place force fields nearly everywhere. They can be used as platforms, shields and mirrors.
The game is inspired by Portal, which means: no action, environmental puzzles, first person perspective.
Made with Unity3D.
IMPORTANT: I took the game out of the compo; it's part of the Jam now. The reason for this is that the character controller consists of a script written by someone else (see README.txt).
