Oh okay, I thought something went wrong. :p But if it was intentional, then I said nothing, haha.
Tip for updates in the future: Best not to delete the old version till you are ready to upload the new one. That is what I do to avoid people who try the game find an empty page.
If in any situation you delete the old version and are not able to upload the new one right away, mention it on your page.
Anyhow, I see the demo is back on. :) I will give it a try.
(Edit: I think the empty page is more a problem for my games, since those are HTML games, playable on the page.)
