I liked the graphical style and sounds, although the keyboard clicks were a bit too intrusive after a while. Also wished it had tab-autocomplete to save typing evertyhing by hand!
Uses a custom font that is missing a lot of glyphs, so a lot of the text doesn't render. The apostrophe for instance. But then on some files the contents are just 'misisng unicode character' glyphs.
I'd check for errors in the console, but something in your build is capturing all keypresses which is quite annoying, so all browser controls are broken (and I also cannot rezoom the page - you've shipped this hardcoded too large for the page, so its off the edge of the screen).
I recommend re-uploading without the 'take all browser keypresses' if possible, then we can a) resize the screen and b) try to debug what's gone wrong with the font.
