Pojuko
Pojuko has a campaign game that offers three training levels or you can start right in at a level called Baby Steps. There are twenty chapters to the campaign overall and you are able to save the game and come back to it later. Use the mouse to determine the angle of your jump and press the left click to determine how much power you want on the jump. Depress the mouse button to jump and try to be upright when you land or you could fall off the ledge! You must collect all the coins (indicated at the bottom of the screen) in order to grab the finish flag and move on so don't "jump the gun" and get to the end before collecting every coin on the screen.
