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.

The movement of the fox is AWESOME! It is nearly perfect XD. If you make another game, make sure you do the same thing...whatever you did!

Nothing I hated about this, this was just awesome. I liked how you didn't really have to worry about getting hurt and you could just breeze through the game relaxed. Nothing that would be annoying or stressful and everything seemed to click together well. Yep, this was a very relaxing game. Maybe not so much at the end because you actually had to move around and time your jumps but that was still very fun. The wings were a nice touch, didn't really affect gameplay but were fun to have. Its awesome to have stuff like that. But is it even possible to get all the darklings? Anyways, good game and you can't go wrong with mushrooms.

It's possible to get them all, but you need to plan for it a bit.
