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.

Collect all that junk and there ya go. :P I unlocked all the teleports and completed the boss area. I didn't figure out how to go in the walls to get the mushrooms/levers so I am stuck there. Also, I didnt kill the darklings.

I am trying really hard to enjoy this game because everything in this is beautiful. But I cannot stand the control reactions. He keeps running after I let go and doesn't jump until 5 seconds AFTER I told him to.

It's possible that the browser you're using is causing input lag, or you're low on memory. It isn't normal for it to do that, so try another browser and see if that helps.

Fuzziness takes something away from this

Honestly, the best thing about this game for me is the music and sounds. Very appropriate and atmospheric. I could listen to the music, the rain and thunder all the time. That alone scores very high for me.

But what I don't like about this is the fuzziness. I don't want to sound weird or anything, but this is a beautiful game visually and audibly... when there is SO much travel in the game, it gets very see everything. When you move left and right through all the trees and everything else, the background, trees, rocks... everything is blurry. Aside from a little bit of a headaches and dizziness which doesn't bother me too much, it takes away from the pure enjoyment of your game.

Regardless, great job... 5/7

Kajenx responds:

Yeah that fuzziness is the bitmaps moving at a slow (for a video game) frame rate. it has to be pixel perfect, and it doesn't have motion blur, so I know what you mean.
