Woahh this is amazing! The platformer movement is extremely satisfying, and great concept and mechanics. Also the sound effects and voice really help the atmosphere.
Thanks for the feedback! Yea I may have realized level too could be a bit too difficult, but to anyone reading, the way to do it is to get two of the spiders onto the big boxes, then one spider attached to the ceiling, and then to swing along the ceiling to the exit :D
