Time Machine

Time Machine is the eighth level in Geometry Dash. It was rated Insane when it came out but changed to Harder in Update 1.9. It was also not in the lite version.

Description
Time Machine starts with a few easy jumps, followed by some tricky triple spike jumps. After about one third of the stage, the player is introduced to the mirror portal, which flips the direction of the screen. The level ends with an anti-gravity ship.

Secret coins

 * The first secret coin is after the second blue gravity portal. After you pass the portal and jump pass the spike, jump on the platform and collect the secret coin.
 * The second secret coin is located on the first ship sequence. Fly through the center block and then collect the secret coin; sounds easy but hard.
 * The third coin is after the blue mirror portal. Flipped upside-down, on the last yellow pad, don't jump on the platform. Be prepared to jump midair on the purple jump rings. Also be prepared to jump past the two-spike.

Trivia
