EDIT: Well IU was stuck here for ages but of course I figure it out ten minutes after posting this thread. Anyways, here is a text solution. Kind of vague, but it may help. Cheers.
You need to use the top left tentacle in combo with a bridge above the top spikes to pull the creature from the start to the right on the bridge, briefly release him, the capture again with left tentacle so he has energy to spring back to the left. As soon as you reattach him and he is coming back, move the bridge so it now ramps up to the top left light. The use the right tentacle to pull him through the middle (with a couple of ramps as buffers). Then while attached and hanging from the right tentacles, I make a ramp below right tentacle that leads to the rope and bottom middle light. With the momentum from rolling down this ramp, you can make it to the exit as well.
