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 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.

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.

An enjoyable, all around platformer, William and Sly is a basic, well-balanced game.
For a game I barely, just heard of, it sure did surprise me to find that I've been playing for about ten minutes. I'm not kidding, I've been playing the game for ten minutes straight it was so entertaining. It's complex level design help you study the environment, and notice the beautiful backrounds, that... yeah, I'll admit are a bit blocked by the foreground, but the overall look is great. The animation is well done too, although, the fox's movements could have been developed a bit more, like when he's falling, I turned to face the other direction, and the fox moved like he was on solid ground. I also don't understand the reason why it's called William and Sly, what the hell does William do, besides sit on his ass, and asks his pet fox to do stuff? But where this game won me over, was it's creativity... giving a simple tale of fox helping his master, a fantasy-styled edge, that I strangely, kind of liked. The medals were thoughtful too, making a simple-sounding task like, kill 5 darklings, into something a bit more difficult. and the wings were a nice touch, even though I knew what to do as soon as I read the sign. Overall, this game doesn't have much as far as plot and gameplay are concerned, but it's pleasant imagery and creative unlockables keep you playing until you think you've finally finished.

I like it!

This game really should have a better picture... I mean, i saw the game's title like a BILLION times under my current game, but it looked so boring, i never clicked it! But now i know, that ANY game can be good, ESPESSIALLY on newgrounds.

Asside from that, to me, the game was a bit medival, in some odd way, it took me four or three hours too pass it, and i gotta tell you, the story line wasn't bad... Even though it was kinda... let's just say, "Random" to have a fox collecting flying colors to restart ancient stones with wierd markings on them wich can make you teleport from one to another, the game made sense.

So i just thought, the game has great sound, great graphics, great eye-boggling extras, awsomely hidden secrets [wich i diddn't find all of], nicely done storyline, a very constructive map, an open space, breath-taking enemies, AND a challenging boss, i STILL find it missing something... I just can't figure out what it is...

Great, but I have a flaw.

You said this game was not complicated or..... not too complicated like the other games..... this IS complicated for me... I don't know if I am just not able to cope, but if you could just make the levels a teensy weeny bit shorter, with less goals and take it at one step at a time, i guarantee people will enjoy this game more. Also, I played it for about 5 minutes then i got bored of playing, as I didn't know anything really about the game or how to complete the level. I don't mean to put you down or anything, but this is just a bit of constructive criticism. And for this, I will ignore the previous comments and give you a 7. But apart from that, brilliant graphics and music. Thank you for looking at my comments on this great game, I hope to get your reply soon.

You just need to find all of the Runestones to complete the game. If you hit Shift there's a helpful guide.
