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.

This game's animation is very smooth and the game over all is fun to play. I would suggest improving on the backgrounds as they can get a little blurry because of all the detail put into them. well done

Good game, great graphics but extremely challenging especially the end part with the snake. Doent seem to have a story other than getting specific items but nevertheless is still great to play


Rated 5 / 5 stars

great times...

I realy enjoyed the game! It doesn't get boring after a while so well done!
Euh keep going like this ^^

but I don't know why it is but I completed a few medals, but non of them is actualy flashin and on my profile I can't see them also not...
Do you know why this is

thx anyway for the good times


Rated 5 / 5 stars

very nice

The last boss is a lot easier to beat if you realize he alternates between top and bottom with his bite so collect the fairyflies from one half while he attacks the other


Rated 5 / 5 stars


That was great. I loved it! It was so simple yet fun, the best mix. If you aren't being paid to do this sort of thing, you should be, i reckon...
