Switch, a puzzle platformer by Scott Addelsee, Jemma Barnard, Kate Fierek, and Tom Saunders, is like Sonic CD, if it were designed by the team that made LIMBO. You'll be switching between the past, present, and future to collect keys. Moody atmosphere and clever puzzles are hampered by wonky jump physics and unnecessary "switch" limits, but Switch is a game well worth your time.

I think that everyone, if only for a second, has considered the possibilities of traveling through time. Sadly, we don't have the budget for a DeLorean. So it's up to State Of Play to offer us the next best thing: the fast-paced reflex-testing microgame-fest that is A Short History of the World, a beautiful game with finicky mechanics.

In Timemu, you control Timemu, an emu with control of time. Timemu (or "Tim" for short) is just trying to find a home, but must use his powers of temporal self-duplication and navigate several platforming levels to do so.

A casual portal-physics game that's a well-polished piece with concepts paralleling the Flash version of Portal, as well as other titles like Shift 2 and Cursor*10. But instead of being a simple portal manipulation game, Epsilon explores two other physical properties aside from spatial relativity; time and gravity!

Chronotron is a platform-puzzle game with a really innovative (and addictive) twist. If you're a fan of time travel theory or if you enjoyed any of the amazing time-based games (Timebot, Time Raider, and Super Earth Defense, in particular) from our replay-themed game competition last summer, then you'll love Chronotron.
