TRI is not typical by any measure and instead charts its own path to puzzle gaming greatness.

Though TRI lacks the polish and presentation of the more popular Portal titles, its sheer accessibility and serenity mark it out as something genuinely different, and as such deserves to be noticed.

Regardless of comparisons, TRI: Of Friendship and Madness is a fantastically executed return to the well of first-person spatial tinkering.

Great trip beyond ordinary human reality attracts gamers with its eccentric and brilliant visuals and amazing logic puzzles. [Issue#247]

A nice idea and solid implementation of the triangles usage. Highly recommended for the fans of the genre but I can't say the same for the rest of the gamers.

TRI shows a clever concept but is afraid to explore its depths and lacks a decent narrative.

I never put down a puzzle game before I complete it, but TRI broke me on level 12th out of 16. I got bored much earlier than that, though. Unfortunately, the game is not only beyond hardcore, it’s simply rude to the player. I doubt that most of you will appreciate this sort of masochistic experience.
