"In 2008, the largest particle accelerator ever created, the LHC at CERN's particle physics lab in Switzerland, was activated for the first time. The research obtained from this experiment has revolutionized the way we think about science. Un-answered questions that have puzzled man since the dawn of humanity are finally being answered. Are there extra dimensions? What is dark matter? Is time travel possible? Epsilon Experimental Sciences Research Facility aims to discover the potential of this whole new world of science, and you have been appointed as the primary test participant."

Going with what seems to be the current trend, I've made my version of a portal game. The challenges are based around solving tasks using various fictional technologies discovered as the result of the LHC experiment, primarily wormhole manipulation. Other methods include gravity shift, time reversal, and general cognitive dexterity.

I started this a while back and planned on coinciding it with the release of Valve's Portal, which coincidentally was around the same time CERN was planning to activate the particle accelerator. Unfortunately Epsilon still wasn't ready by the time Portal came out and the LHC still hasn't been switched on, so I decided to leave it until now.

Thanks to Geier Arnold for the original soundtrack, and for tirelessly helping out in the beta testing process.

NOTE: If you are experiencing problems with lag while freezing the ball, try turning off the ghost rooms by pressing G.




Mental Aerobics!

This was a well built game. The puzzles are good for those that want to stretch their logical ligaments. It's got a great soundtrack; very ambient. The graphics exceed those of some professional puzzle games. Mostly, I love the story flow. The science experiment backdrop has been used, but you put a nice spin on it.

One thing I noticed was how some of your puzzles were designed to make one intentionally over-complicate their strategy. If I were to give a piece of advice for this game it would be: Keep your strategy simple.

I'd love to see a sequel of Epsilon with bigger levels and possibly multiple balls.


the ghost rooms only helped a few times though. But this game isnt very portal-ey so i think youre safe.

Was the last level just for fun?


This game consumed a lot of my time today. The sound effects and music are awesome, the gameplay is almost flawless (found a few gltiches). However, I couldn't figure out how to beat Level X :(


I lov everything about this...

only, I can't get by 5b, there's no momentum to get the orb right under the teleporter...
