Use A and D to move and W to jump. Use S on a platform to drop down to the platform below. Press R to restart a level.

When you gain the powers of time, click the left mouse button to create a bubble that slows down time. Anything that is touching the bubble will slow down. Clicking on the bubble will destroy it, and clicking somewhere else in the level will move the bubble to that spot. In later levels, you'll get another time-altering power. After you find it, use the right mouse button to stop time completely!
