Sure! Here's an example of a game that meets your requirements:
In this game, the player needs to be AFK (Away From Keyboard) for exactly 30 milliseconds to win. Once they achieve this, an alert will appear saying "Congratulations, you won!" and confetti will be displayed on the screen for 5 seconds.
Note: Since this game relies on timing, the 30-millisecond duration might seem nearly instant to the player, and it's challenging to actively participate. Nonetheless, it follows your specified requirements.
