The instructions are all in-game. (Click on instructions) Hint: The balloons on the bean sacks and anvils don't harm you, it only harms you if you hit the main anvil or bean sack with the front of the hang glider.
I thought up the idea for the game but credit to club penguin for the theme. This worked well on scratch 1.4 but when I uploaded it it went really slow. Play in full screen for faster play. There are a lot of bugs now I have uploaded it but it was fine on scratch 1.4. It might work better on a faster computer ...
