I love the aesthetic.
Couple nits:
I have no idea how I expected the browser back button to work, but whatever it did do surprised me a bit. During gameplay, it might be nice to have an "are you sure you want to go back?" before it exits.
I'd recommend running spell check on your in-game messages. I already saw "Weilding X" instead of "Wielding X"
I'll give it a further go.
The number of RPG players who think they're playing a 'rouge' is too damn high. It feels almost atmospheric that wield is misspelled.
I just grepped the source and wow, literally every instance of wielding is spelled wrong, including variable names. I've updated it, thank you (will push it once HN is done thrashing my VPS). Will also have a think about how to improve the back button thing!
