Okay so I made a full walkthrough But I wrote it on blogger I would copy and past it to here but then it would do all those question mark things. It took a fair while to do all the images and write it so please tae the time to read it the link is right here http://gamewalkthroughscheatstipssecrets.blogspot.com/2012/01/william-and-sly-2.html I hope this help
That game annoyed me to no end, I was playing it for about 5 hours combined to beat it, found a walkthrough map, checked it, checked it again, and again. Then I realised that I glitched the game by getting too many keys at once, making it so after everything else was collected, there was still two unopened chests. The game is still good, but you've been warned, don't make my mistake.
