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.

Rated 4.5 / 5 stars

Good Game

This game is super! Only one problem, it is very repetitive and gets a bit boring. This music, graphics and detail is very great though.


Rated 4.5 / 5 stars


This game has such an deep graphic that is possible to describe it as artistic, the boss and the rune system was very original and yet simple enough to surprise even non hardcore players.
Waiting for future works or a sequel


Rated 5 / 5 stars

Maybe For an Hour.

I would have given this game a 7. Agreeing with most before me, this game did become rather repetetive, and lacked a certain something. However, something about the intricate details makes me want to keep playing. The tiny details,
right down to the thunderstorm sound affects and the vibrating camera when around powerful magic, makes me want more games to look like this. I think that Lucas has a huge potential with this kind of Platforming game - I love the music, the animation, and the layered backgrounds. He is definately skilled. I am certainly looking forward to see if he posts another game here!
