devs: five bucks for a (not-so) simple minigame plugin

A very very long time ago in the alpha and beta days, I occasionally used Minecraft classic to play the super fun lava survival gametype. Many of you probably weren't playing at this point, but it was tons of fun, and I was wondering if it could be done with command blocks. Here's an explanation of tyre game.



A group of players is stuck into an enclosed map area. They then have 5 minutes to do whatever they can to get into safety, while trying to hinder other players. At the end of 5 minutes, lava starts flowing down from the sky. When the lava comes into contact with a block, the block will "melt" after a small period of time, defined by a random difficulty set at the start of the match. If a player touches the lava they die. Last player standing, or survival for a set amount of time is the win condition.
