Thanks. I'm glad you liked the game, too.
Interesting about conditionals. I don't think I've ever heard that before. (That site you linked to gets a bookmark, too. I'll do some more exploration there later, to see if I can learn some more.)
...and now you got me confused about what to do with the window again.
(Could I say "through", or is "of" more natural?)
"disapperance" was a typo. Fixed.
will/shall: I suppose I thought it sounded more royal that way, but you're right. It's better with "will".
into: Fixed.
