Well done! As you said, a few minutes of entertainment out of it -- but probably more actually, quite a few laugh out loud moments. :)
Reading the comments I see there are some other endings, I got the standard one, and the master one. But I think I'm missing some other ending (related to that locked door I'm guessing).
One part I was assuming I would have to do which might be nice, was escaping the house before the time runs out?
Nice work again.
