There are many ways to fall off the map from the connecting bridges between rooms, forcing the player to restart.

After the 3 yellow lights section you activate the circle and it reveals a checkpoint next to you. If you jump out of the circle before the cutscene starts, you can fall through the rotating block and into the abyss.

Not a major issue, but it's possible to jump out of the blue circles before the ball "charges up", but after the charge of the circle has gone, forcing you to restart.
