Clear Air

Clear Air is a two-player collaborative game in which you and your partner must work together to purify the air by keeping your garden in good condition - if all your plants die, that's it, game over! Grab your watering can to feed your plants (careful - it only holds so much water!), your pickaxe to fix areas of ground damaged by acid rain, or your mallet to squish those pesky smog-bugs before they grow too big and overwhelm you!

Use either Xbox controllers (left stick to move, A-button to perform an action/select), or keyboard to play:

  • Player 1: WASD to move, Space for action/select
  • Player 2: Arrow keys to move, Return for action/select

Alt-F4 will exit the game.


  • To switch tools, move to your tool rack (player 1 on the left of the field, player 2 on the right) and hit "action"
  • If both players are close together, "action" will swap the tools you are currently carrying. This is really useful as it refills the watering can!
  • The watering can only hold enough water for five uses: swap over tools (either at your rack or with your partner player) to refill it!
  • Smog bugs do more damage as they grow - squish them quickly to prevent them doing too much damage1
  • Acid rain will damage your garden - fix damaged ground with the pickaxe. Once an area of ground is gone completely, it cannot be replaced!
  • Watch out for the YEET bonus!
