Spleef Arena with Classes

My friend and I have made a Floating Spleef Arena for you to enjoy! You have to spawn several times to spawn at the right place. When you spawn in the right room, there will be different signs. It is the rules and a button to select a class. You will have to stand very near the place you want to be, or another player might take your place. There are 7 different classes: Spleefer (Zombie) you will get to break the wool blocks immediately. Placer (Steve) you will get to place wool around the map and a "Flower Power" weapon. Ranger (Skeleton) you will get a "Sniper" (Bow) with knockback to shoot others. Demo (Creeper) you will get splash potions of slowness, 5 splash potions of nausea and 64 spawn creeper eggs. Knocker (Wither) you will get a "Knocker" (Brick) with knockback to punch others. Ambusher (Enderman) you will get 16x16 stacks of ender pearls. Swifter (Spider) you will get Spider Punch (Spider Eye,) 16 Cobwebs, 16 potions of Swiftness 2 + Leaping and 32 splash potions of Mining Fatituge.

Remember to turn monsters on!!! (There is a server.properties file in the download.)

Note: All classes have a "Bad Spleefer" except Spleefer, because he already has a better one.

Recommended players: 4, but you can play with 2-8 players.

Notice: Only break the wool in the Spleef Arena.
