Checkpoint 4

Checkpoint 4 (aka Canyon) is the checkpoint after Checkpoint 3 and before Checkpoint 5. It was used as Checkpoint 3 (Version 0.8.0), as seen in the Smash Hit Gameplay.

Description
The main color scheme is red, the glass is red and is the first to introduce hammers. This checkpoint has three stages, and the difficulty becomes noticeable. This checkpoint mostly includes spinning objects. The spinning blades in Stage 1, the hammers and (Formerly) Crankshafts in Stage 2, and the sheets of glass that pop up and down, thick glass bars, spinning propellers, shifting glass walls that move to the rhythm in Stage 3, have proved to be a challenge. The glass is also double-thickness (e.g. glass bars and shifting glass panes) in some parts.
