Hey guys, I’ve started work on a possible William and Sly 3. Follow me on facebook for updates! https://www.facebook.com/LucasPaakh/


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 ngads.com and ads.newgrounds.com 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.


This is a simple game. But that's not a bad thing. It's very simple to understand, and the controls are very tight and responsive. The atmosphere is great, and very easy to immerse yourself in. The boss fight seems a little... unexpected, and I don't think it really adds to the game much, and kind of breaks the atmosphere. Regardless, this is a very nice game to play if you love exploring and completing things. There's so many secrets to find, this game will have you glued to the screen for hours.

This platformer is different in that you cannot die, as this game focuses pretty much entirely on exploration than combat.

That aspect doesn't take anything away from the gameplay.

After playing this game for so long, I am ready to give my review.
Storyline: 8.5/10: I like the simplicity of this game, it is entertaining and it can be used as a stress reliever if you are stressed out over school work. The storyline is simple, all you have to do is to try to unlock everything in the game.
Music: 7/10: Nice pick of the music, fits in the atmosphere of the forest. However, maybe a few more soothing piece of music will do.
Graphics: 9/10: The graphics is beautiful for 2009, as no 2D games can have such a stunningly nice graphics. It didn't lag for me. The polygon counts and the framerate was well processed.
Controls: 9.5/10 The controls are simple to understand.
Overall: Fantastic job in creating such a beautiful game for Newgrounds, as this is a Masterpiece, good job in getting a Daily Feature. I also love the simplicity of the game where you can collect items and defeating bosses. I did complete the game with all the achievements, nice work!
