Thank you so much for playing it and the review! You're completely right about the UI and the password puzzle. I definitely should've made the password applicable both in caps and without, and using a checkbox instead of a button was a miss. Many of the issues you've encountered are due to my unfamiliarity with the engine (the url-textbox thing being lockable only in part was something I considered but couldn't figure out and get working in time), and I hope to improve as I practice.
Again, thank you so much! This is exactly the kind of feedback I've been looking for. <3 (Please say hi to your cats for me!)
