Sword Practising

This is my first project in a while. It is a Sword Practising Room where you practice your swords skills. When ever you click one of the 4 difficulty buttons mobs spawn from dispensers. The amount of mobs which spawn are chosen by the difficulty:
Easy- 5 Mobs
Medium- 8 Mobs
Hard- 12 Mobs
OMG- 28 Mobs.

There is currently some issues with the map mainly just with Mob Spawning. Some mobs will suffocate in the walls.

Play on at Least Easy!

There is no main goal (besides Killing as many mobs as you can) to this map so feel free to create your own goals.

Thanks,
