Waking up in a strange facility, college student Sam takes control of a device called the Catalyst; a device that manipulates space-time and alters physics. Inspired by the critically acclaimed "Portal," players will use the Catalyst to change the laws of physics with whatever they happen to fire upon. Players will walk on water, create floating stepping stones, and much more!

Absolutely beautiful design, graphics and concept. Do you have a date when you think it might be close enough for a demo or full release? Thank you for this and all of your work.

For those interested in TesserAct, I took the time to record gameplay of the public demo version 3.0. At the same time, I am also supporting the ongoing Kickstarter campaign Propelled Bird Software is currently running for the full commercial release of the game. You may find my video on my personal channel:


I hope you all enjoy this playthrough of the game. At the same time, I hope it strongly encourages everyone who has been following TesserAct for some time now and is as excited about it as I am to get onboard with it; keep watching after the gameplay to get filled in on the Kickstarter. This game deserves our support! If we all do our part together, then TesserAct shall triumph!

Going to be doing my bit for you guys; The whole concept and look of this game really fascinates me, plus you guys have been doing a lot of ground-breaking work in UDK that needs to be recognized. I'll be recording some 'Let's Play' videos on my personal Youtube channel; might get a series going. Channel might be small, but I like to do my bit for the Indies who make awesome things like this. ;)

It's a very nice game, I would like to play it, I can't wait for playing the full release! Are you in Greenlight? Do you mind if I share it in my YouTube channel? I'm Argentinian and I would like this game to reach the Spanish community! :)

We currently have a "concept" Greenlight, due to the fact that Valve requires us to have a ready-to-ship build to set up an official greenlight, but please feel free to share us around! We can use all of the help we can get to let people know about our game!

So it's basically Portal 1 and 2 and physics and space time stuff combined?

Protagonist looks a lot like Chell.
