Weekend game: Null Op

Hey, I spent this weekend working on a fun little game idea instead of slaving away at Shade. The weekend is over and so is my time with this game (or at least until Shade is finished) so I thought I'd share it with y'all. Let me know what you think!

Play Null Op

Basic run down, it's tower defense and there are currently two weapons, a mine and a turret. Click on the buttons on the bottom to create a building and click again on the map to place it. Right click on a building to sell it for half it's price. Try to prevent the waves of enemies from destroying your base.
