This is a very interesting mechanic and it adheres to the theme well! It's a shame that it's too short, but good job for being able to make the submission!
The controls are a little finicky at this state of the game but I believe that if the controls could be smoothed out this has to be a potential to be a great action platformer with some puzzle element to it. Perhaps it would be interesting if there was some sort of benefit the player gets while the blob is attached to it?
The art is gorgeous and a pleasure to look at so great job with that! :)
