"I'd play this for a couple of minutes"

Some pieces move, some pieces fall, a piece or two might end up tumbling some more. At least that's how things usually go during your average game of Reaction. You swing your paddle left and right in order to push the pieces towards the evacuation shafts, gaining some of that precious little time before the play area inevitably spills and it's game over.

"Aha", I hear you say, "so it’s a physics puzzler of sorts!" And that is correct. You can play it alone or with a friend in multiplayer, you can go at it in short bursts or try to crack those elusive high score spots.

Here's what's included:

  • A single and/or multiplayer experience
  • Six power-ups to help you get through the evolving levels of difficulty
  • The option to add faces and expressions to pieces, turning them from cold shapes into cute little geometrical folk
  • Versions for Windows, Linux, and Apple. *

Speed, difficulty, controls, sound, and music are all customizable. By default, you use the left and right arrow keys in a singleplayer or when playing as player one in multiplayer, while player two controls their paddle with the Z and X keys.

Version 1.1 of Reaction, the physics puzzler where geometry falls from the sky and you move it around with your rotating paddle, is out now. Besides some much needed bug fixes, it comes with a few quality of life improvements and an in-game manual.
