This update adds another feature which I think is very cool: The ability to challenge other players! So there are basically multiplayer games now. Currently, this is the same as a normal game, however, only one player can win and once that happend, the game is over for both. Please tell me your feedback and look out for possible issues as this is obviously a very new feature. I also fixed a bug concerning the Player Hider (again).
If you have any further ideas, please let me know, as this update adds the last thing I really wanted in the plugin.
