Tap to start a trampoline and end it. When you are done drawing double click the button to drop it and try to get it to the flag. If the ball gets stuck, press R to restart the level. If you don't know how to beat a level, press H to make a hint appear, which shows you one possible solution. There are currently 30 levels (6 worlds). On the map you can use the left and right arrow keys to move levels. The circles on the map represent the levels, and they have 4 possible colors. If it is white, that means you have not unlocked that level yet. If it is red, then you have unlocked it. If it is green, then you have beaten the level. And if it is blue with a star, then you have beaten that level with the least possible amount of trampolines.
Thank you DD-8861. Your work is true art. Sorry it is so glitched and laggy.
