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.

Loved it

It is one of the best games i have ever played
I loved the music, but most of all i loved the artwork of a fox and the concept.
The animation for the fox is really good, except the boss was a bit hard
i think the medals may be a bit hard to get.
the rain toggle is on the M in the bottum right corner
Thanks for the pleasure of making this game
It rocks!!!!!!
Go sly

Great game

Yea, the person under beakerboy really is an idiot. It's a great game, nice graphics, particle effects, the landscape is enormous, it might actually take me some time to do this! It's an amazing game and i give it 5/5 10/10.
