This is a mob fighting game that I built after getting the idea for it while testing redstone properties. It has 40 total rounds and a series of 5 different arenas, each with different terrain. The full list of rules and explanations is inside. Good luck, and remember, feedback is always appreciated and will help to keep me motivated!

Update: Added the two new arena's to bring the total to 5, and made the door in the 3rd arena more sturdy.

Additional Notes

If the sound of slime bothers you, simply go to peaceful mode for a moment between rounds to temporarily despawn them for a bit, or play without sound.
