I'm glad you liked and I'd be happy to explain how it works. All of the things you mentioned, from the visuals to the bugs, are due to how the slime is built. I'll attach a gif to help explain it because it is a bit obtuse. The slime itself is not one solid object, but a set of 12 points arranged in a circle with one extra point in the center. Each of the 12 points has two spring joints, one connecting it to the adjacent point and one to the center point. The camera then renders triangles between these points to make it look like a solid shape. Because the slime is completely hollow, the individual points can sometimes get stuck on platforms or the whole structure can collapse upon higher impacts. I tried to build the game around this which is why I added the respawn feature. Hopefully I explained it well enough but if you have any more questions feel free to ask!
