When the bar fills completely you win. Hold the space bar to fill up the bar. Press the down arrow to change where you're looking. Click the big box to use the camera to chase off the bird.
If the game breaks click the green flag a couple of times. This is my first game so don't expect too much. The timer is from Top Down Shooter and the power is from by @dobekindathiccdoe here's the game link https://scratch.mit.edu/projects/684369799/ The sound effects are from @Sebastian_I_Guess. The "voice acting" is done by myself.
