Whoa, for a moment I thought she would die.
Anyways, I love games like this. They're simple and usually made by creative minds.
I loved the "story", but I think there should be a limit to the hints so you don't exploit it.
I only used about 5 hints throughout the game, always to clear out the last item(s) of the level that I missed.
Something like a timer, where you have to wait 5 minutes to use another hint, or a timer that increases (like for the first hint, you have to wait a minute and the more hints you use the longer the wait).
