The art and ambience are stunning! I can really tell a ton of creativity and artistic skill went into this.
I did also end up with the wrench softlock though, and only knew to restart after reading Jyunaut's comment. Additionally, I'm having an issue with the key where I'm unable to tell if I'm doing something wrong, or if there's an issue with my browser that's preventing it from working.
Edit: I was able to complete it! The issue was actually my lack of patience on one screen, not a browser issue. Overall, easy top marks for both ambience and innovation!
