The randomness of explosions was actually a bit frustrating. Also it would be nice to have items interact which each other. Remember the glued pens? What if you could unglue them using the scissors? However I really liked the foreshadowing in the text box. But I do agree with another commenter in that the intro should only play on your first attempt. Otherwise it's just a waste of time.
Also what were the hidden words when you clicked on the sign again? I wasn't able to figure it out.
