Paperio.Space (Version 3)
Control Keys: Arrow Keys to Move
PaperIO.Space is also known as Paper.IO 3 game. If you want to play its old version you can play Paper.IO here that loads the 2nd version by default and you can change the mode to select the first version or other versions.
How to Play: Move the character that leaves a string behind and it wraps when you reach back your origin. This way you capture the area you moved to. However, if you or other players touch the string while you are away from the origin/home, then you die. In the same way, you can also kill other players by touching their string if they are away from the origin to kill them.
Version 3 is very competitive and you may always find all other players very close to you. So you must be very careful and active while you move, else you die.
