Breakthrough

Breakthrough is a very hard demon created by Hinds.

Overview
Breakthrough is a 1.9 level created by Hinds, it is one of the first 1.9 levels ever to be uploaded in Geometry Dash, it is also considered to be one of the hardest levels ever in Geometry Dash too.

Gameplay
Breakthrough's design and concept is similar to Electrodynamix however, with a 1.9 touch however, the level uses 1.8 slopes, 1.7 colored blocks, and decorations of both versions. The level is quite tough and difficult due to the fast wave mode, confusing cube mode, crucial timings, memories, and a very hard ship mode despite it's difficulty.

User Coins
This level contains 3 user coins however, the second user coin arguably the most hardest one to get:
 * The first user coin is located at 29%, at the first ship mode. The player must carefully go through a gravity portal where the coin was located, which is under an "L" shaped 1.4 block. There is a spike near the portal so be careful.
 * The second user coin is located at the first mini wave mode at 74% on the top of the gravity portal. The player must get the second coin with crucial timing or else, will crash.
 * The third user coin is located at 92% at the last mini cube mode. The player must jump off into a ramp, skipping the normal route, heading straight to the last user coin. There is a blue jump pad that leads the player into a blue gravity portal, going through the normal path.
