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.

Awesome stuff.

The graphics are gorgeous, and the gameplay is fun. The only problem I had is that it felt SO big. But i guess thats a good thing.

A cute little game with nice graphics and absolutely no real point to it. And yet for some reason I can't stop playing it.
The graphics are great, the controls are fluid, and the game is surprisingly addicting. In spite of the fact that fetch quests are normally extremely boring, I found myself running back and forth across the landscape trying to track down every last mushroom. And even after all that, I'm still down one stupid mushroom you merciless bastard.
Anyway, a great game. 5/5,10/10.

The game world is massive.
I have never seen something like this in a flash game
