How To Play
First off you do indeed need 2 players there is no AI sorry 
You will start in a box where both player will read the rules (hopefully ) and
click the ready up button. once clicked you will be teleported to where you place
your ships. You must place one 5 ship, one 4 ship, two 3 ships, and one 2 ship with the sand.
Then go back into the box you got teleported to. From there you can play by clicking the buttons to shoot
you will be able to see your ships hit when they turn into a red block.

Things to take note
YOU MUST PLAY IN 1.7+ 
There is no turn squence so you could rapid fire if you want but that would be cheating.
There a notication when a player has shot, and if somebody fire twice it will throw the
notice off, so try not too. 

Rules
Theres no rules because you wont listen to them anyways. Do as you please.
You MUST enjoy....or else....
