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.

Great, GREAT game.

Even though, this is one of the better games I've played on NG, I've found 2 little bugs.

1. It didn't register my medals. Very frustrating. (But I guess thats not really your fault either)

2. (POSSIBLE SPOILER). When I finish the game, and go back to my "owner", he says "You look pooped" or whatever. After a while, the screen then turns black, and you get to see your stats.

Now if I "continue" my story, all is good. However, if I go back to that guy again, and do the same thing, and THEN click on continue, I will spawn infront of the same dude (because of the auto save), and it'll immediately send me back to my 'stats page'. Thus, leaving me, in a never ending circle.

Easy way to fix this, is to start walking to the 'left', before you click 'continue', and than you should be far enough to continue again. (if you get what I mean).

Graphic and gameplay wise though, this game is awesome. Allot of secrets to find, allot of stuff to do. Nice unlocks.
Overall, a crazy great game. I loved it.

Alright well,

I don't see what good about this game. The graphics were alright but that is about it. The controls are what really got me. I would just like to hold down the arrow keys but the fox just stops for god damn reason.

I know that this review is most likely going to be rated useless seeing is how everyone seems to love this game but I just don't like it. Sorry mate.

I really enjoyed the game, exploring the various platforms with my nimble fox sly. The graphics are great, and you some how manage to transform something as simple as running around into a fun activity. the addition of the wings made things even cooler.

the only problem i have with this game is the "boss battle" at the very last rune. the fairyflies take a while to respawn, the boss is very fast and takes up most of the area. I do love a challenge, but activating the last rune was about as much fun as slamming my hand in the door.
That is my only complaint and otherwise I would say you made yourself a truly creative and wonderful game!

The last part scared the hell out of me, but I like this game and for the most part, it is very soothing

Great game of life

This game was a great game, It seemed beautiful at some places, and the graphics were just right, the zooming out option did make the view awesome unlikely of other games.

I hope there will be a sequel of this dramatic lovely game sequence.
