Definitely some Limbo vibes here. The environment is so good, especially the lighting effects and the spider. Great work!
The camera sometimes trails off to one side, so I think there's a bug somewhere in there. Honestly I thought it was intentional at first because it trailed off towards the spider and looked super cinematic! But then it never came back and I couldn't see myself anymore haha.
Another random thought: maybe instead of jumping, the caterpillar could just climb up onto vertical surfaces as well? There could be some interesting platform design that makes you traverse vertically or even upside down.
