Thank you! I felt like it would be highly unrealistic and feel unresponsive if the laser couldn't damage other lasers and the player, so I added it. And considering there is a lot of stone left even after 1000 tiles I knew some people would want to continue playing. At the moment of writing this, a friend is playing the game and is trying to clear out the entire game area. He is at 5500 tiles out of around 6000 and has played for 45 minutes.
