Incredible game and a really cool implementation on the theme. It has one of the most unique mechanic I've seen in the jam and it's a really fun and polished one to boot!
Aiming and spiting the slime strategically to gain even more inertia is great fun, and I greatly enjoyed the stage hazards factoring in the boss fights. The presentation is also slick and hell, giving a weirdly repulsive (in the best way) feel in both the in-game graphics and the cutscenes (amazed you even managed to fit in cutscenes).
My two small issues were technical, as I had some slowdown from the second boss onwards and I falled out of the stage in the third boss.
Great entry and one of my favourites so far! Will be following you guys!
