Time Machine

Time Machine is the eighth level of Geometry Dash and Geometry Dash Lite and the second level to be rated "Harder" as of Update 2.0.

Description
Time Machine introduces the mirror portals, which flips the screen and plays the level in the other direction. It also reveals the pink jump rings, used after the third secret coin. It has lots of short anti-Gravity parts, 6 in total and has 3 mirror portals. It has two cube segments and two ship segments. It is the only level to end in anti-gravity.

Secret Coins

 * The first secret coin is located after the second blue gravity portal at 12%. After the player passes the portal and jumps over a spike, the player must jump on to a small pillar. Instead of taking the safe route by dropping to the floor, make a controlled jump onto the second platform and collect the secret coin. The player must make sure that he waits a split second before jumping to the second platform to ensure he does not hit the spike situated above the platform.
 * The second secret coin is located at the beginning of the first mirrored ship sequence at 36%. the player must fly steadily through the centre block between the spikes and then collect the secret coin. The blocks that compose the top and bottom of the big block are fully solid, even if the player does not make contact on the white line of the block. Those solid blocks allow the ship to fly straight through the centre block.
 * The third secret coin is located at 69% immediately after the upside-down segment. To obtain it, the player must not jump off of the platform at 68%, but instead fall. This will bring them to a different gravity portal, followed by the final coin, but be they must be prepared to jump on two purple jump rings They should also be prepared to jump past the two spikes on the regular route.
