Even if the player clicked early, it is still possible to perform an action a little later with Input Buffer Time.

Many games use this technique to avoid stressing the player if they clicked at the wrong time.

Examples:

1. Celeste - If the player presses the "jump" button just before touching the ground, a buffer time is activated. If the character touches the ground before the cooldown time ends, the character still performs the jump action

2. Hack'n Slashes games - If the character is going to make a block, the buffer time is activated. If the enemy attack collides with the character's block, before the time interval ends, a parry occurs during the action.
