Various Gameplay Hints
Some buttons are hidden in the upper-edge of the screen, so keep an eye out for them.
You can replay the levels at any time if you want to get the high scores.
The sort of ragdoll you fire depends on the sort of cannon you're using, so make sure you check before you pull the trigger.
