For this week’s Fun For Free, I found a cool Portal-inspired game called Epsilon.

Epsilon is a browser based game that was created for the Armor Games website by EON. It’s a puzzle game with similar gameplay elements to another web game called Portal: The Flash Version, which is basically a 2D version of Valve’s Portal. The biggest difference in Episilon is that you don’t have a character to control, so you are just moving portals around a screen and using a few other abilities to beat each level. To complete a level, your ball must collect all the orbs and go through the exit. There are numerous obstacles in its way, such as time limits, walls, and Gravitational Shift Units.

The presentation of the game is nice and clean. It doesn’t do anything spectacular, but it doesn’t do anything necessarily wrong either. The music is kind of bland and gets repetitive fairly quickly, but you can turn it off.

The levels in Epsilon aren’t very difficult and the game itself is fairly short, both of which definitely hurt the game. But the game does continously add new elements and restrictions which keeps things interesting. All in all, it’s a pretty fun game and will give you at least a few minutes of enjoyment.

Play the game here.
