World of Goo 2 to Unleash New Features and Challenges

World of Goo 2 release for the 2D physics puzzle game has been announced for Linux, Steam Deck, Mac, and Windows PC. Thanks to the creative minds at 2D BOY and Tomorrow Corporation for bringing this epic title. Due to make its way onto both Steam and Humble Store soon. Mark your calendars, fellow 2D physics puzzle fans — the World of Goo 2 release is coming to Steam on April 25th, and it’s bringing some seriously wild stuff with it. Whether you played the original or this is your first dive into the sticky madness, get ready for a weird, wonderful, and brutally tricky ride on Linux.

Think You’re a Puzzle Pro? Prove It.

This isn’t just a game with more levels — it’s throwing down the gauntlet. Due to offer three new challenge levels that are ridiculously hard. We’re talking controller-throwing, brain-melting tough. Even some of the devs can’t beat them. So, if you think you’ve got what it takes, these levels are made just for you.

Meet the Goo Crew

In the World of Goo 2 release, the goo balls have evolved. There are brand new types of Goo with weird and wonderful powers. Jelly Goo. Explosive Goo. Shrinking Goo. Even Liquid Launchers. Each one changes the gameplay in some epic (and sometimes chaotic) way. So, you’ll need to get creative and experiment to figure them all out.

What’s That Sound?

The soundtrack? Oh yeah, it great. There are over 47 new tracks, almost 2 hours of music, and it’s all due to the help from over 50 musicians in the World of Goo community. It’s haunting, it’s beautiful, and it also sets the mood for every twist and turn.

Endless Challenges in the World of Goo 2 Release

The title comes packed with five new chapters and over 60 fresh levels—each one more clever (and more evil) than the last. Plus, you can also chase down 30+ wild achievements, and for the first time ever in a 2DBOY or Tomorrow Corporation game… there’s an options menu.

More Goo for Everyone

Therefore, no matter where you play—Steam or other platforms down the road—everyone will get the same content. That means the three very-hard challenge levels, achievements, updates, while offering the gooey goodness will be shared across the board. So yeah — World of Goo 2 2D physics puzzle release is almost here. Wishlist it now on Steam or Humble Store, call up your puzzle squad, and prepare your fingers. The Goo is coming to Linux, Mac, and Windows PC.

SUMMER DEV LOG 3: VIDEO EDITION

I’ve basically recreated my softbody game in Unity. Next I’m going to work on adding the “sticky” button where it creates breakable springs attached to objects on contact.

Intern report - 2D and 3D JavaScript physics added to Turbulenz

My name is Luca Deltodesco, intern at Turbulenz for the last four months as part of my four year MSci Maths and Computing course at Imperial College London.

I've always been interested in, and worked with in my spare time, the technology behind games; Turbulenz then, was a perfect fit to work with emerging, and powerful gaming technology for the Web. Following my application, and a face-to-face interview at the office in Guildford I felt this is where I wanted to be.

Following my induction, my first task was to begin development of the Canvas PhysicsDevice, adding ray-casts and convex-sweep support so that all the weapons in the Quake 4 tech-demo could be used outside of the plugin. After completion of this task, I began to work on the full implementation of the Canvas PhysicsDevice available in the SDK today!

Implementing the PhysicsDevice was a big project, helped greatly by having had previous experience with 2D physics, but there were a lot of new things to learn. A lot of the time was spent working out the most efficient ways of implementing the physics for JavaScript and tuning physics parameters for the best behaviour.

During the implementation, I worked on a side project in Python - which first required *learning* Python - for the optimisation of collision meshes in the Quake 4 tech-demo. This involved a fair amount of computational geometry that eventually found its way into the WebGL PhysicsDevice, optimising convex hull collisions through abuse of the triangulated hull topologies, and ray testing of convex hulls by using the triangulation.

After much perseverance, the PhysicsDevice was completed (Minus some constraints) together with the Physics Benchmark SDK sample.

My next task was the Draw2D library. This library was originally written for the Score Rush game, and required tidying and optimising before being released into the SDK. I made use of Chrome's profiling to analyse the bottlenecks of the API and was able to make some quite drastic speed improvements. We later had a meeting to discuss changes and extensions to the API which turned into the Draw2DSprite object, and drawRaw interface.

The Draw2D SDK sample was created to demonstrate the capabilities of the library.

Another aspect of the original Draw2D library, was a full-screen bloom and distortion effect. These were generalised and separated from the Draw2D library, and after adding the Gaussian Blur effect, Color Matrix effect and related utilities, the TextureEffects API was born.

Turbulenz now had fully functional 3D physics for both Canvas and Plugin, but with an expected influx of 2D games, including the Save The Day game, it was clear that the Turbulenz SDK should also provide 2D physics. I spent a short time on researching existing solutions including Box2DJS and Box2DHTML5, as well as my own library compiled for JavaScript, none of which proved to be performant enough; it was decided that I should implement a 2D physics library for Turbulenz which would be high performing, and fit in with the rest of the APIs instead. As a formal project, I wrote up a Project Charter and initial API specification that other members of the team could read over and give their input after which I took a well needed holiday.

Returning from my holiday, I had only 4 weeks left to implement the 2D physics; I took a pragmatic approach of breaking down the project into discrete, unit-testable tasks so that I could develop the library quickly, whilst being confident there were no major bugs. With the experience of the WebGL PhysicsDevice and Draw2D, I could see immediately how best to implement the API for speed in JavaScript from the get-go, and everything was completed in time together with the documentation and the three 2D Physics samples.

Looking back, I thoroughly enjoyed my time at Turbulenz and gained much experience and knowledge.
