Unfortunately, the Lycos Ads interfere with IE and stop it from displaying Pixel Dizzy properly (though, with IE 'properly' is a relative term).
It works fine in standards-compliant browsers.
I can't really fix the problem — not without moving hosts — so I've configured the site to display as plain text when someone with IE tries to look at it. It's not pretty but at least it works now.
Back on topic; I actually have a more enhanced version of EfZD on my hard-drive with extra levels and stuff, but it's in .gm6 format atm and I don't have Windows anymore so I can't 'compile' it into an executable. If someone has everything needed and knows what to do then I'll email it to them.
Ok, thanks to FireFly, the newest version of EfZC should be up. It's unfinished, so you might find quite a few bugs. Aside from that, there are a few new levels, greatly improved graphics, and extra puzzles.
