Well that didn’t take long: just a few short hours after David Brackeen’s ./SHEXAGON text-adventure mockup was posted, two readers jumped out of the woodwork with playable versions.

The first, from Casey Griggs (turn down your speakers before clicking that link), pictured above and playable online, adds extra genuine CRT effects to make the experience that much more remarkably retro.

The second, downloadable for Windows/Mac/Linux from Todd Little, plays it more aesthetically straight but adds an actual timer to the response system, giving you just a few short seconds to submit your lefts & rights before getting crushed to a pulp.
