Fit for kings, two dimensional war. You can find me at the store. Soldiers in passing on front lines. This game really tests your mind

I am in a game, use me to test your aim. The center is rarely the way to go, some sixties will win you the game. Don’t ever get me in your eye, you’ll feel massive pain. Make sure you don’t score past zero, or start your turn again.

I arrive uninvited when effort is high, a bubble of betrayal, no tears, but some may cry. Born from your grind, or a poor shoe choice, I silently scream with a fleshy squishy voice.

Even when I’m by myself I’m always a pair. Only those with a Sharp mind know what I am.

Golden crescent fruit, Doth slip from its yellow skin, Sweet within, dost hide.
