Sure! Here's an example of an HTML file that implements a simple game based on your requirements:
This HTML file sets up a game where you are represented by a blue cube and SCP-173 is represented by a red cube. You can start the game by clicking on the blue cube, and then you need to avoid blinking for 7 seconds. If you blink, the screen goes black, and you are killed by SCP-173. You can replay the game if you choose to.
Note: This implementation doesn't fully include the mechanics of feeding SCP-173 or cleaning its container, as it focuses more on the blinking aspect and the restart functionality. However, you can modify and expand the code according to your needs.
