I've recently completed v3.0 of Tom's Halls:
This version pretty much "completes" the game - literally, as there is now a game complete sequence :-D It has also been much overhauled and improved, with several dastardly new screens including my favourite, "Temple of DOM".
Best played in Firefox, Chrome, or Opera. Don't even try in IE8. IE8's DOM scripting is about as fast as Microsoft's uptake of W3C web standards. <ouch>
It's pretty hard but there is a cheat!
