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 game!

However, through the whole game, there was one thing that bothered me a lot.
The boss, was WAY too hard. I'm still batteling it as i'm writing this comment. Its annoying and unpredictable.
A couple of things you could've done to make it easier:
-Let the view zoom out, so that you can actually see where the boss is comming from.
-Develope a way that will defend you from the boss, instead of dodging it.
-Make the boss smaller.
-Make a pattern in the boss movements. For example: Down, middle, up, up, middle,down.
One question, why does the boss look like the crocodile from donkey-kong?
So yeah, Next to the boss, well done on the game, simple yet fun to play.

Well done

Great artwork, great story. The boss pissed me off!
I am wondering: is the music supposed to be intermittent like that. I don't think it should be, it's good music. Also, why are the birds singing, even though it's raining?
Very relaxing (except for the end)
