Testing jumping insect and knife spider enemies
The large ball shaped insects will try to fly towards you using their tiny, pathetic wings and the knife spider will stab anything it comes in contact with, including other monsters. There are secondary mechanics like the little jumping worms the orange insect leaves behind and the fact that these enemies act like physics objects and roll down or up depending on what physics settings I gave them. In a circular arena like this that's easy to predict, but that's not always the case. Also, I didn't do this on purpose, but the bones on top and bottom and other tunnels are just the right size for the knife spider to jump through them, even against gravity. That was a fun discovery while testing.
