Hi There!
Here is our spleef arena. Most of it is made by hand, only the roof is made by McEdit. I made it all by myself "nope" only made the snow layers and copied some buildings. So I decided to give him credits anyway.
The instructions are pretty basic:
1. On the first layer (the top one) you must destroy blocks under your opponent with golden shovel, which u get from chest.
If your opponent falls - he must go through the door and continue to the next level.
If you win - you must notice the chest near the stairs and get from it golden apple and chest plate, go down the stairs and continue to the next level.
2. On the second layer Instructions are pretty same as on the 1st. Only when you fall, you just go to the base and continue to the next level.
You must grab one bow, 16 arrows, a shovel and try to kill your opponent + try to make him fall using the shovel.
If you win - jump out of the seconnd floor to the first floom and continue to the next step.
If you loose - go to the base and w8 for your opponent till he jumps out and grab his supplies.
If you got killed - you lost the game.
3. On the third layer you must grab 16 arrows and bow(optional) and try to kill your opponent.
if you die - you loose the game.

Thank you for your atention! :D
