KillCounter is a plugin that kills the player executing the command after a time in seconds of choice. This plugin would come in handy if you'd want to to make a special adventure map or a gamemode, for example.
The plugin is fairly simple to install and configure. To install the plugin you must place the downloaded .jar file in your server's plugins folder. To change the time untill the player is killed simply open the config.yml file with your favourite text editor program. The file is placed in a folder created by the plugin on first run. The default time is 120 seconds or 2 minutes.

Sorry for the lousy download and not using github. Still looking into how to make the repository work properly.
