The respawn loop seems a bit broken. When clicking the alert, it doesn't respawn me, but I die again. Also, I only hear the audio after clicking in Chrome. Advice to always put something to interact with on the page when it first loads up so that you get browser permission to play audio.

Works but nothing is explained, its a good idea to convey to people what the different items do, the game ending pickup should be more visible that it will end the game, like using a skull or something.
