There was once a game called Narbacular Drop. Soon, it gave way to Portal, one of 2007's best games. Following in that same vein, ArmorGames is hosting a new browser-based puzzler called Epsilon. Where Portal is darkly funny, though, Epsilon is all business. And it also screws around with time.

You control two portals that can be moved around the edge of a room. Your goal is to drop a ball through these portals so that it collects tokens and eventually enters a portal to the next stage. However, you can pause time, rewind it, flip gravity, and do all sorts of other crazy tricks. It plays much like a refinement of the gameplay seen in Portal, and that's definitely a good thing.

Make sure to turn off ghost rooms and crank down the quality, as they can be very processor intensive.
