Echoplex is a first-person puzzle game in the tradition of Portal and Antichamber.

This demo has 5 levels to give you a feel for the game - we'd love to hear your feedback in the comments... :)


In the Echoplex, you're followed by an echo of yourself who repeats everything you do. Activate a switch to unlock a door, and your Echo will activate the same switch a few seconds later, locking the door again.

Your Echo is always getting closer - and if it catches up to you, the game is over. You must use strategy and timing to outsmart your Echo and escape the Echoplex.



The controls are look, walk and run. The aim is to get to the exit of each level.

Although the controls are simple, the real challenge of the game is learning to work with your Echo.

To succeed, you will need to think ahead and use precise timing. Each level has a theme - pay attention to the level titles, as they may provide clues.



Based on player feedback so far, we are working on adding these features to the game:

  • Greater range of movement, e.g. jumping and sliding
  • Impossible objects / Euclidean space
  • Multi-storey levels
  • Transference ability, i.e. swap places with your Echo for a limited time
  • Weapons that can freeze, slow down or obliterate the Echo

What else should we consider? Please let us know in the comments/discussions.

We're now on Steam Greenlight - if you like Echoplex, please vote for us here:)
