I actually feel like it might be better to name this block.Slime. @T14Raptor I understand we've been adding the Block suffix for consistency, but maybe we should remove them from all blocks? The stuttering you get from block.SlimeBlock is a bit awkward.

I think we should.

I added velocity logic for non-player entities, there's just a small issue

when you throw an item at a horizontal angle, it just slides across (which is not vanilla behavior)
