...Two Birds With One Stone

As a farmer who still has not seen the worst of the upcoming global warming threats, you are going to protect the valued field from the blood-lust crows, with the use of a one (and only) stone. Good luck!

Use [WASD] to move, your mouse to pick up and throw
No birds are actually killed in the game, they are just scared away
Warning: mouse controls are very sensitive in the WebGL version.

Special thanks for helping to come up with a backstory to Vivian Truong
