I haven’t played much of Dyad, outside of a quick level or two. Its Tempest style gameplay is something I should enjoy, but generally don’t. It isn’t the first game to riff off of Tempest with a psychedelic style (that’s Jeff Minter’s wheelhouse), but it was the first one available on the PlayStation 3. Controlling a particle, players slingshot through a tunnel taking inspiration from the Large Hadron Collider. Slingshotting and lancing through other particles extends one’s combo, and thereby score, which, at its core, is the name of the game. I’ll likely play this more, at some point.
Dyad was developed by Shawn McGrath and published by Right Square Bracket Left Square Bracket. It was first available on PlayStation Network July 17, 2012, with a PC release following on April 24, 2013. Perhaps best of all though, is the PC commercial.
