Splitting

Splitting is an ability.

Splitting can be performed by pressing the button. When splitting, all your cells which are big enough will split into 2 equal parts, the part that splits is shot with a great speed in the direction that your cursor is facing.

To be able to split you need to have at least 35 mass.

Merging
Your split cells will have the acquire the ability to merge back together after a certain time after they have been split. To merge two cells back together, just steer one into the other. This can be done by putting your cursor in the middle of the two, so that they will go into each other.

There is a cooldown on merging your cells together meaning that you'll have to wait a certain amount of time to merge after splitting. The cooldown time is calculated as 30 seconds plus 2% of your mass (ex. Mass is 50, cooldown time is 31 seconds).

Strategy
It can be used as a weapon or as a tactic to survive when you are in a dangerous situation.

Splitting is great for managing the mass of your cells by reducing their size so they lose less mass over time.

Splitting makes you cover a wider area, move quicker, and your camera becomes more zoomed out so that you can see your surroundings more efficiently.

Splitting can be used with ejecting mass to transfer food between your cells.

Bare in mind that a split cell, unlike a single one cell, must be 33% larger than the cell it tries to consume. One single cell only needs to be 10% bigger than its target.

Also, when you split, other players can eat the small cells you split into, as now you are not a single cell anymore, and that opponent that is smaller than you if you aren't splitted could have been easy to eat.
