Good job! Each time it gets better, even the error of collecting many bulbs from one table lamp has disappeared.
But nevertheless there is no limit to perfection!
You forgot to put the image for the background before the gameover from the basilisk: Window0.png
I tried to replace this image with a plain black background, but it did not help, the error disappeared - but the text is unreadable, because it is black under it has no text fields. Oh
However, if you don't attack the basilisk - but just go for it, the text is fine. Alessandra's petrification works just as well.
That's why there is one minor bug left in the game. Without attacking the basilisk you can pass the game comfortably. I don't know if you will fix it, but it would be nice.
