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.

Very Cool............

Nice graphics


Rated 5 / 5 stars

Oh wow

Ok so I didn't want to play this but after seeing it up for 3 day's I was tempted. Its actually a fun game Its pretty cool how you don't have a health bar. So its really hard to loose haha. I did notice the fairyfly's respone after a bit and that was pretty cool. Great game for sure.


Rated 5 / 5 stars

Played a bit, loved it.

The controls feel great, animations are smooth, backgrounds impressive. It reminds me of knytt stories, which is definitely a good thing.

Glitch found

I pressed some key (maybe space) and suddenly i returned to the main menu. Then I clicked continue and the fox respawned at the left top of the map.
I walked left ( am i stupid) and fell off the whole map. He is falling all the time. So i have to restart the whole game.

Anyway, this game is cool.

WHAT?! That sounds really crazy...


I tried some stuff and figured it out. That's a pretty crazy bug. You managed to hit some combination of tab and enter. What were you doing?! LOL, anyway I'll upload a fixed version.

I loved it.

I was really frustrated with the boss, but eventually figured it out. The only thing I'd really like to be different is the fact that if you miss a darkling when you activate a rune, you can never get it and have to start over.

I'd also like a sequel. :D
