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

Rated 4 / 5 stars


Visuals are unique, music is beautiful, gameplay is addicting. However I see no reason to unlock runes.

Art is great, game is fun.

It could use more action, but other than that, great game. I quit after a while because it became quite repetitive to just jump around in the forest. I think more enemies would make it a lot more bearable. I didn't play long enough to get to the boss, though.

Great artwork, though! Very nice world, not even sure if it's tiles or art-based. I think the challenge level of it is a bit too low, so you might want to make the hidden areas harder to reach. Not much harder, just a bit. Other than the lack of action or challenge, this is a brilliant platformer. Make more!
