Great concept and the controls work nicely, the suggestions I do have are mostly focused on the visuals.
Having the player be functionally in first person makes it a bit difficult to gauge exactly when you'll collide with the blocks, so I would recommend having a player character slightly in front of the camera on the tracks. Also with the blocks all being the same colour it can be challenging to differentiate which layer each upcoming block is on, especially from a distance, so I would recommend having the blocks alternate between different colours to help set them apart.
Great job!
