A downloadable game for Windows, macOS, and Linux

Explore a vibrant universe of cubes.  Solve puzzles by manipulating your environment.  Advance through distinct worlds as you master the connections between positive and negative, creation and destruction, dead and alive.  And if you make a mistake, don’t worry, you can undo all the way back to the beginning.

Obversion is being made by just me, Adrian Marple (aka Marplebot).  I left my job at Google to try to make it as a solo indie game dev, despite not direct prior game making experience.  What you see before you is my first attempt at making a full-fledged game.

Saw you at Indiecade where our booths were nearby and I finally got to try it! Interesting game mechanic; I love the infinite Undo and also the fact that you have a linux version!

Thanks! And nice meeting you at IndieCade! In retrospect, I'm surprised that more continuous movement games don't have this sort of undo system. It's very common in puzzle games with grid based movement.

Finished playing the demo.  Can’t wait for the full version.
