Epsilon

Epsilon is a special flash game that will build on the success of Portal. You have two wormholes that must be placed in a such a way that it can teleport the ball to collect various orbs and return to a portal once done to proceed to the next level. The dual world are very confusing. when you try to move a wormhole with the mouse you get an inverted world showing the other end of the wormhole. Later on you realize that we have features like time rewind, gravity shift and stuff like that. You can start the game with space bar, which can help to make infinite loops that must be used correctly to add momentum to the ball.
