♥Things you are told and things that are obvious:
Eat blobs smaller than you to grow in size
Use the space bar to send 50% of your mass flying at a blob to eat it
Use the W key to eject some mass
Viruses cause large blobs to explode into many smaller parts
♥Things you are not told and things that are not obvious:
Every cell experiences a passive loss of mass in relation to their current size (larger cells lose mass much, much faster than smaller cells)
Score is simply the largest mass you have had this current life.
Holding down the space bar will cause you to cover much more distance when you split
Feeding a virus 7 times will cause it to create another virus which will launch out of the current virus and go about 5 units in distance
Viruses also decay in size
Viruses do not always cause the player to split; there is a cap to how many pieces you can be and if you are already at that thresh hold you can simply consume a virus as though it were any other cell
At certain sizes you reach milestones which unlock new abilities (you can choose to display the mass of your cell by selecting "Show Mass" in the options when you name your cell):
▲ Size 32: Eject a blob of size 16 to increase your passive movement speed or feed a virus
▲ Size 150: Create another virus by feeding an existing virus 7 times
▲ Size 150: Large enough to explode an existing virus
▲ Size 1900~: Due to passive loss of mass it becomes nearly impossible to retain size by eating neutral blobs;
▲ Size 30,000: The Maximum Size Limit (The dev changes this quite often, previous maximums have been 22,000 and 28,000)
