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, but I have a flaw.

You said this game was not complicated or..... not too complicated like the other games..... this IS complicated for me... I don't know if I am just not able to cope, but if you could just make the levels a teensy weeny bit shorter, with less goals and take it at one step at a time, i guarantee people will enjoy this game more. Also, I played it for about 5 minutes then i got bored of playing, as I didn't know anything really about the game or how to complete the level. I don't mean to put you down or anything, but this is just a bit of constructive criticism. And for this, I will ignore the previous comments and give you a 7. But apart from that, brilliant graphics and music. Thank you for looking at my comments on this great game, I hope to get your reply soon.

You just need to find all of the Runestones to complete the game. If you hit Shift there's a helpful guide.

Honest mark.

My memory is not that great to rember all the holes and nooks and crannys, would have been nice if a drawn path was made following the explored areas so I know where I was and been and maybe revisit those areas again as well. In addition that the chest would be marked on the map following their discovery, and maybe a color indication wether I opened them or not. Just too many boxes to try to remember and not worth bother traveling all the way back to explore and area I dont remember and already have been.
The ending boss was a bit challenging, I do enjoy the fact that no harm comes to you hero, so stress is less of a factor and you can enjoy the exploration of the game.

Controls were great. I like the option that you can use either the WSDA or the Arrow keys (for left or right handed players). Graphics were great and the controls were fluid and reacted when I wanted them to, not like some platforms that delayed in control because you have to wait for the character to finish it's programed move. The music was mellow and the storm ambience was perftect. The finish was cool but anti-climatic, was expecting something bit more, or a short cinimatic ending.

Over all, programer/inventor/author/storyteller (how ever you wish to label your self or all of the above) great platform, I enjoyed it.

I have to agree with some of the others. Whilst the game itself has good graphics, a nice theme and an excellent amount of effort put into it, it's not the most fun thing in the world...
The gameplay is incredably basic and for that reason quickly becomes tedious and unchallenging. I liked the smooth movement of the fox and falling from great heights, but this was perhaps the highlight when compared to the game itself. It's not a bad game, in fact for a child's game it's very well made. However, it is certainly not "outstanding" and I feel there are far better games on this site. You should be very proud of it though and I admit I'm definitely being biased because of its massive score. Well done though.
