How to get best ending: First go to town. Then go to the park. Then click on the the forest. Go left and drink all the water in the lake. You will see a crack. Keep clicking on the crack until you get the treasure.
The fourth level on the third row in medium had a retarded flaw, why would he put the laser that repeatedly goes up and down (it's in the middle, toward the bottom) if it can't touch you?
On F2, they think we're so dumb we would use the bottom two bouncing pads when instead we could make a platform for the orbs to go into the pipe directly.. -_- lol
