Sure, here's a simple game implementation using JavaScript and HTML:
In this game, there is a game board represented by a div with the id "game-board". There is also a flash button (represented as a red circle in the center) with the id "flash-button". The objective is to tap/click the flash button when Beavowl is visible in the vents.
When the flash button is clicked, it checks if Beavowl is currently visible or not. If Beavowl is visible, it displays an alert message saying "Beavowl rips off your face!" and resets the game. If Beavowl is not visible, it displays an alert message saying "You scared away Beavowl!", sets Beavowl to be visible, hides the flash button, and resets the game after 2 seconds.
You can test and play the game by copying the code into a single HTML file, opening it in a browser, and interacting with the flash button.
