Renardes.7z

"Get out of the room, alien-zorching meatheads, because you'll need your noggins to bust this conundrum [...] Four mice out of five!"

"I didn't know it was possible [...] for a person to die of confusion, until I watched my brother succumb to this atrocious game."

"Never before has a puzzle game actually been ABOUT puzzle games, you know?"

Renardes is here! Unfortunately, most of its instructions were lost in the depths of space from which this fiendish and completely original puzzle came.

Use the arrow keys to move the double-square frame, and Z or Space to change the covered tiles in a red-yellow-green cycle.
