Checkpoint 4 is the checkpoint after Checkpoint 3.
The main color scheme is red, the glass is pinkish red and is the first to introduce hammers. This checkpoint has three stages, and the difficulty becomes noticeable. The spinning blades in Stage 1, the hammers in Stage 2, and the sheets of glass that pop up and down, glass bars, spinning blades, shifting glass walls that move to the rhythm in Stage 3, have proved to be a challenge. This later leads to the next checkpoint, Checkpoint 5.
