You can also destroy the boss without firing a shot if you hide in the top left corner of the boss screen. He keeps knocking rocks down and they fall on his head! Takes time though.
Having a trigger-happy cop constantly discharging his firearm in my whore room would totally kill the mood. I don't know how Clarence's father stands it!
11-type "key" on keyboard
14-swing the tree back and forth violently until key falls out
15-take your cursor down the orange path from penguin to penguin without straying outside of the path
24-same idea just more penguins to get to
Annoying levels: 8, 9, 17, and 22 which was super annoying.
25--just set up an infinite loop and you are golden
Clever game overall
