I like the way the camera closing up to you when you stop, making you feel impending doom without having to display a timer. After the first death and the game restarts, there's a big gray box blocking the game window. See the screenshot below. Is that part of the game's puzzle, too? I tried on 2 different browsers, same result. Also, after I figured out the player had to die to use its dead body to continue the game, the 3-minute wait seemed like a long time. Perhaps add some fun things to do without having to move while the player waits for its "reborn?"
