This is level 12 of the Low Power Tunnel.
You have to walk through entirely power tiles made rectangular platforms. But don't worry, they are mostly half-lit up most of the time.
You can treat it as a normal rectangular platform jumping level as first. Jump high, and then land while navigating yourself in midair. Then, suddenly the power tiles all shut down! You have to memorize where the power tiles are, or just see where the stars are absent. When you finish the middle part of this level, the power tiles will then half-lit up again, allowing you to finish this level.
As usual, the Pastafarian's light bridge can let you see where the power tiles are, making this level easier.
