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.

Animation, composition, colours, game play... just stunning.

What would make it even greater is if a different landcape would be loaded each time one starts or restarts the game. Would put some variety into it. I kinda missed the old landscape, though. *tear*


Rated 4.5 / 5 stars

you should make the ending easier i stopped playing bcause of it otherwise great game


Rated 5 / 5 stars

Excellent game.


Really. It's not that hard. He attacks across the bottom, then moves across the bottom without attacking. Then he attacks across the top, then moves back across the top without attacking. Rinse and repeat.

It's sad seeing bad reviews because people couldn't figure out the ridiculously simple pattern the boss follows. Idiots...


Rated 2.5 / 5 stars


Yeah, well, great animation skills, and beatiful sounds.
But nothing more than that :/,
Just running around map collecting meaningless things
and then at last, the boss... the boss could have been much funner.
add somthing else than just 1 attack and 1 break, the attacks were totally
random and dint make any ''Rotation'' / tactics you could use.

People find this review helpful!

Cool game overall

I loved the graphics, I found this game very relaxing, and after playing most through I listened to some music and carried on exploring, it was simple yet fun, the setting was really nice to be in so I just carried on playing. The only thing is there wasn't an incredible amount of varying in gameplay which maybe this game could offer in a sequel... like more missions from William. I managed to get all but roughly 6 mushrooms and 1 key.

I think it would of been great if at a certain amount of mushrooms you could of got a power that made secret tunnels visible, but that's just me wanting to complete the game easier :P.
