Hey guys, I’ve started work on a possible William and Sly 3. Follow me on facebook for updates!


This is probably my best game to date. I wanted to make something more accessible, as most of my flash games have been too complicated for my family to play. :3

I really hope you guys enjoy it, I think it's the most effort I've put in to anything. A big thanks to everyone who helped me test, and Tom and NG for the sponsorship!

As always, leave a comment! I love reading them.

EDIT: The game has version detection, but YOU NEED FLASH 10 to play it. If you have trouble loading the game, please send me a PM with the details.

EDIT: Because nearly everyone is saying they can't figure out the boss's pattern, I've made a slight change that should make it more obvious. Once the game update is approved I'll let you guys know and you can try again with the new pattern. *Alright it's up now*

If you're getting a black screen after the Newgrounds and Particlasm screens this applies to you. This might also help with the loading bar freezing. This was posted by a Kongregate user (thanks Knork):

"If the game does not load past the ads make sure that and are not being blocked in your hosts file. Which is located under C:\WINDOWS\system32\drive rs\etc
If they are, uncheck the "Read-only" attribute and edit out those two lines."

If this works for you let me know.

The atmosphere is amazing, the music and the BG and art complement each other so beautifully, my only problem was that the music did not run for long enough, perhaps you could make a nice taunting/dark and moody ambient piece that plays subtly between the nice a magical current music tracks.
My second problem would be the boss, it took me nearly seven minutes to figure out it had a pattern, before which i had thought it followed the player.
Then my next problem would be the ending, which was - in honest words - rubbish. It needed a cinematic ending, probably best if it were showing a new predicament setting up the players for another adventure for our little fox?
Just an idea.
I would also like to PM you on another subject.
Anyway great game, lagged a little but still the best i've seen since, well, ever!
