Sure, here's a simple implementation of the game you described using HTML and JavaScript:
This code creates a simple game where you control a character (represented by a blue rectangle) on a 4x4 grid. The goal is to click on the center grid within 30 seconds to achieve victory. If the timer reaches 0 without clicking on the center grid, a jumpscare animation will be shown and the game will be over.
Please note that this is a basic implementation and can be expanded upon to include more features and gameplay elements.
