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.

Needs more beef

This is a fine engine you've built for this game. But, there wasn't enough substance to it. There were no instructions on how to kill the little mud monsters or anything, which I had to figure out on my own. Also, the music, when it played, was very nice. Very melodic and soothing, but it would just cut out and there'd be silence. More sound effects are needed too. Oh, also-- Where did the boss play in? All of a sudden there's an evil cloud snake eating your fairies. There was nothing that really made sense. I seriously HOPE you make a sequel, the gameplay for this reminds me of Ecco the Dolphin, for some reason so, please continue this game series.

This game is the reason i signed up NG.

Fun and addicting until i got to the boss, omfg, i got so frustrated and somehow beated that sofb, really, the boss got me so pissed off i had to register to tell you this! It also scared the shit out of me when it came with its mouth open :D.
But otherwise the game was good.

The animations are smooth and I like the fact that you play as an animal and not a special mutant animal with special powers. The music was calming too.

The game ended too abruptly for me; This seemed like a pre-task before we got into the real game and so I was disappointed when it ended. It would have been awesome if you could continue the game as the man (or fox - depends on the storyline and how you could justify the man doing nothing :P).

Other than that, great game and I enjoyed the professional feel that I got from the game (no glitches that I came across and good animations with good collision detection)
