Easy Points in Level 1
When you jump over a barrel, you typically are awarded 100 points for your effort. If you jump over a barrel while positioned directly above the top of the middle ladder attached to the third tier (in the game's first level), you may also gain several hundred additional points. That will happen in the event that the barrel starts down the ladder as you are in the air, due to your jump. It's a great way to obtain a higher score than you otherwise could.
