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.

Fantastic Game!!

This is by far one of the best flash games I have ever played. The graphics are beautiful; the sound track sets the mood; the platforming Easy and intuitive. And to those who say the boss fight has no pattern just aren't paying that much attention. Hint: After the snake head goes across the back and you're on the bottom, watch where it goes and on the next pass go to the top and watch where it goes. . . Anyway, this is a great game and I really hope to see more from you in the future!

A beautiful game.

One of those rare gems you find on this site. The graphics, soothing melody(which reminds me of the music in fable when you open one of the secret doors) and WIDE open play field, are just all done perfectly.

The boss is very, very frustrating until you figure out its pattern. It took me a good 10+ minutes to get it down. Try this;

1)Stand on the platform just above the runestone.
2)as the boss passes with its mouth open, jump to the very bottom of the pit then jump back up to the same platform.
3)It will now pass under you for its next pass.
4)The pass after that it will be on the same level as you, so drop down to the bottom of the pit.
5)Climb back up to the same platform again and rinse and repeat.

Note: If a fairy appears on the top platform you are on your own. Try to keep that same pattern going and you should be able to beat it. When it passes with its mouth closed it can't hurt you, but indicates what side it will attack from next. Most of the fairies will appear on the mid level to the bottom.

I do think the boss take away from the game, but will not deduct a mark because the game is so well made otherwise.
