****SPOILERS!****
I had one key left and I got a bad ending. Did I miss something? The end screen didn't leave me any choice but to close the window/tab.
UPDATE: I found where I didn't use the key. Will update soon.
The "bad ending" is actually the only ending in this game. If you had a key left, it would have just taken you a special room where you could have obtained something nice, but not another ending.
Thanks. I finished the game twice just in case.
