When 20 seconds passes, the player unlocks poison. Poison can be dropped to slow down the enemy, or the player can accidentally eat his own poison and slow down.
I want to show that the player wins after 60 seconds has passed. I thought I would show it as a loop looping the 20seconds 3 times but that would be incorrect because the player can only unlock the poison once.
Would the best way of showing this be to draw a rectangle around the entire diagram and just state (after 60 seconds, player wins)? - and have it lead to an end circle?
