Thank you for trying it out, if I may ask- did you also try to refresh your browser after starting the game? While it's definitely an issue I have to solve in the future, that seemed to help others who played the game!
And about the intro, I fully agree, the intro is quite long but it's also a part of this specific experiment for my thesis so it's intentional- but- I did add a feature that shows up once you've died the first time, you may skip the instructions with the Key that's showing in the Game Over Scene! :)
