This is a wonderful concept and a really enjoyable experience all round! Excellent work! I really liked the difficulty of it and I definitely will be playing through it a lot. Just as a little point of improvement, for some reason, after the second "death", the game doesn't reset/ do anything for me so I have to reload the browser page.
As further info, I'm playing on a 32GB RAM Predator Helios 300 laptop, Windows 11, Google Chrome, and Core I7 10th Gen chip if that's any help!
