The goal of Bollen (which means "the ball" in Swedish) is to control a purple ball and to move it from one side of a stage to a red flag. You can only move left and right with your ball, so you will need the help of the other creatures in the Bollen universe. The difficulty is increased for each stage and it takes a lot of skill and practice to beat all 23 of them. If you manage to do good you will also get to play the hidden bonus-stages with ridicilous difficulty.
"Bollen" refuses to start on my computer. No matter which settings I choose in the start menu, the moment I press "Launch Bollen", the game simply returns to the directory and nothing happens at all...
