This is level 15 of the Low Power Tunnel.
In this level, there are many large narrow platforms you need to jump on. Fortunately, the power tiles can be seen clearly due to that they are dimly-lit. But the gaps are really big too. If you use the Runner, make sure you use the high jump to jump over the gigantic gap. As for the Lizard and the Jack-o-Lantern, make sure you don't overshoot and land in the void of space!
After you finish this level, a new side tunnel will be unlocked.
There is a cutscene that featured in this level. However, the cutscene won't be initiated when you beat this level. In order to watch this cutscene, you need to go to the Galaxy Map and press on the newly unlocked side tunnel. If you want to see this cutscene, you can go here.
