The dream-like first-person puzzle adventure started as a prototype during Ludum Dare #20 in 2011. It got a good reception and the following year a further developed alpha version was put up for sale. It has now become a full game and today it was released on several major distribution platforms, like GOG.com and Steam.

At a first glance it might look like a more vibrant version of KAIRO. TRI is a much more directed experience though and you'll notice similarities to games like Portal, which it even references in the tutorial. The game has you moving crates, deflecting light, creating triangular platforms and walking on walls to move through 16 stages in order to reach your goal in each. Every stage is a wide space which offers additional replayability in finding hidden idols and beating time challenges.

The game is developed in Unity so a Linux version was almost a given, but it was still nice to see it get a same-day release for our platform. There's an in-game message saying it doesn't support graphics cards from Intel, but I haven't noticed any issues with my Intel Sandybridge Mobile so far.

If you're curious about the game, there's a demo available on IndieDB. Note that it's a level from the beta version though, so the full release will be more polished.

Official About

Prepare for a mind-bending first-person adventure, as you enter the world of the Odd Gods and discover the magical power of the TRI! Master abilities that let you create your own path through an immersive universe full of unknown wonders.

With every twist of a corridor, every raised gantry over your head, every new floor of towers and dungeons in the Odd Gods’ world, TRI challenges you to think outside the box. Empowered by the TRI artifact, you place anchor points on the walls around you and conjure triangular platforms which can be climbed on, walked over and otherwise employed to negotiate the levels ahead. They’ll help you solve puzzles, reach otherwise impossible ascents, reflect light beams and even walk up walls… once you discover how to do it, that is!

A real test of spatial awareness, TRI is a mix of first-person and puzzle gameplay that will push your mind to the absolute limit!

In addition to Humble and Steam the game is also available from GOG.com, IndieGameStand and itch.io. There's also a soundtrack edition available for purchase.

This looks really nice, but Unity engine? I bought many Unity-based games like Rochard, Kerbal Space Program, Gone Home, The Fall, Shadowrun Returns, Wastelands 2.. and all of the games have issues like horrible screen tearing at least. Gone Home is not playable for me at all (tried several workarounds). KSP needs manual fixing of mouse sensitivity and a launch option, and so on.. I'll have to wait and take a very close look at the steam forum before I buy the next unity game for linux.

Edit: I'm on Kubuntu 14.10

I've heard others mention such issues with Unity but I can't say I've experienced it myself. I haven't played KSP, Shadowrun Returns or Wastelands 2 but I've played Rochard, Gone Home and The Fall without noticing that. I've gotten some pretty bad frame rate drops at certain points in The Last Tinker and Monochroma but since I do most of my gaming on a 2 year old mid-range laptop I figured that was to be expected.

Do you know if it's an issue that's specific to certain kinds of GPUs and Linux or is it a more widespread issue? Could be that it's just not very noticeable on my rig. Either way I hope it's something that gets fixed in the near future since there's so many neat games coming out these days that are built in Unity.

What are your specs?

I'm on a GTX760 now, was on GTS450 (which rox), and always had problems with unity games. But I gotta admit that I don't tweak my system for one special game. Either it works or I play another. We have a wide choice of good games on Linux and especially Gone Home was a Sale, so I don't bother.

For anything a little demanding I use my GeForce GT 630M with 2GB VRAM and Nvidia 331.38 driver. I haven't had to tweak anything either, other than to choose between integrated and dedicated graphics. That's true, but I'd be a bit bummed if I had severe issues with something I really wanted to play though.

Did you try playing the beta demo to see if you had any issues with that?

The most disappointing fact to me was that bugs in Gone Home, though well described by many linux users in the steam forum, have not been fixed since release in August 2013.

That is disappointing. I see there's a ton of reported issues Linux issues there. I must have been pretty lucky not to encounter any on my playthrough.

On another note I've put about 3 hours into this game now and I'm really enjoying it a lot. There's a huge emphasis on exploration and you're very free in how you choose to get around once you've unlocked the powers to create triangles and defy gravity. A word of advice though: hit that quicksave button often when you're doing tricky stuff. Otherwise it can be pretty disheartening to have gained a high altitude in search of one of the more elusive idols, only to have it ruined by a slight misstep.
