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.

Can you help me out please?

Great game, bet it fairly easily.
Although I can't seem to get all the mushrooms does anybody have a walkthrough for this?

Well Done!

Wonderfully made! This is the one of the only games to keep my interest long enough to finish. Good job!

Sound 10
Animation 10
Story 9.9

The thing that stands out about this game is the motion of the fox. Truly brilliant and so liquid like. Bravo. If i could meet you in person it would be an honor to shake your hand.


Rated 5 / 5 stars


Easily one of the best games on Newgrounds! The animation is wonderfully smooth, and I liked the storyline. You should be very proud of your efforts.

I would easily shell out 600 Wii Points if this were on WiiWare. VERY well done! :)

ok great game

The only reason that im giving it a 7 is of the fact that i hit shit five times to look at my map and had about 7 fireflys with me at the time a pop up comes up and so i exit out of that...the fox is still running without me...and i run into the thing that eats fire
