Press the flag to start. Move your mouse to move the broom. Don't let the Dinosaur touch the red line on the bottom. If the dinosaur touches the bottom, then you lose. You can bounce the dinosaur off of the broom. Try to break all of the bricks. When you do, you have won!
I followed a Scratch tutorial (Thanks!) to make the first part of this, but tweaked, changed, and added a quite few things. Hope you have fun! :)
