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.

Rated 4.5 / 5 stars

I played this game, then realized I wasn't logged in :P The game is good, but it was a little boring, I decided when I finished. I mean, some parts were exciting, but not all that. I don't remember if this was at the end of the game, as I will say, I was more interested in the gameplay, but I think it might have been an animation glitch. It really bugged me. The gameplay, music, and everything else was great, just like what Stevexal said, but I always think the animation really brings the whole game together. Although, I'm not sure if it was a glitch with my computer, so I won't take away much. I think an appropriate score would be 4.5. I do personally think this belongs on the front page. Just to clear up any mixed messages, this game is great, but not perfect.

What was the animation glitch?! You made me all curious and then didn't tell, you tease. :3

Okay, I'm TERRIBLE at this game. I SUCK. Real bad, and it makes me not wanna play...
I realize how AMAZINGLY good everything is!
The gameplay (which I'm improving in), the art, the music, the big open world!
It's amazing!
Just a bit boring, which is where that half-star comes from.
Then again, I'm not very far into the game.
Maybe it gets better!
