I played the browser version, and it ran surprisingly well all things considered. The platforming around the uneven terrain of the french guy was fun and playing around with the gravity let me experiment with getting around obstacle in ways the designer might not have intended. I love the art of the frenchman, its was very charming. However it was often unclear what exactly the worm would latch onto and start following. I died a few times because the worm switched direction after jumping on to a wall above and I moved the wrong way. You could fix that by giving the worm an eye on one side or something. At one point while I was in the shoe I phased through a platform to one on the other side and skipped a portion of the level (speedrun strats, babee). Not sure if that's a result of weird hit detection baked into the code or if that was just a specific part of the level.
A very creative idea with fun level design, but a little lack of clarity on how the player will interact with the environment. Good work!
Also, what is wrong with this man's feet?! I'm no doctor, but I'm pretty sure that man has too many toes.
