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.

I would not call this pattern obvious.... fuck

People find this review helpful!


Rated 5 / 5 stars

The fact you changed his pattern to an obvious one and it took me so long to figure it out makes me wonder how hard it was before lol. I loved this. I thought it would be a heart tugger and I'm so glad it wasn't


Rated 4.5 / 5 stars

Simply put, this game was downright amazing. Everything down to the graphics and animation to the gameplay. I was actually really disappointed at how short it was. Make me a longer version of this (and maybe with an interesting plot to boot) and i would fall in love


Rated 5 / 5 stars

Amongst the most beautiful flash games I've ever played (and I've played like, 3 games dude(jk)). The smooth and simple animation, the captivating landscape, and the calm and melodic track made it a playable piece of art. The ambient was very inmersive, and the gameplay was simple, yet challenging at times. Simply loved it, still my favorite platformer since it was released. Would love to be able to play it offline, tho.

Awesome game. Loved it a lot, It's neat to see how the metroidvania layout makes you feel as though you're exploring this huge world brimming with interesting things to find along the way
