You need light and utopia to get home after a daring mission! Each level starts with you in complete darkness. Various enemies, shown as spinning circles, float around the level. The largest one will blow up and send out bombs every so often. You have to cover at least 80% of the level with light to trap enemies and move to the next level. To do this, click on your ship and drag it to the edge of a non-lighted area. Your ship will travel along that line. If he reaches the end of the line successfully, that area will fill in with light. If you get intercepted, you have to start over!
