Finished this and loved the whole thing! The stretch/squash mechanic is really unique and I think you've really pushed this concept to its limits with some moderately difficult challenges. You also nailed the jam theme without the more obvious tropes I've been seeing.
Your game has a really simple style but I think the art direction is perfect! It looks incredible with the subtle stylizations like film grain and the CRT-like distortion. These effects were tastefully implemented and not overused (which happens a lot).
Congrats on your submission! I think you've killed it.
