World of Goo, a serious classic that released on Linux back in 2009 is coming back with a little revamp.
Announced on the official Tomorrow Corporation blog post, developer Kyle Gabler goes into some detail about what's coming and yes, the update includes the Linux version too of course.
To be clear on it, there's no new levels or characters and a little joke about "no new battle royale deathmatch mode", this is what they're calling a "gentle remastering" done for fun. Something that's really great to see, as World of Goo is an absolute blast to play but it hasn't really aged well.
The original game ran at 800x600 and they say they've now doubled this, with it now running by default in a widescreen 16:9 aspect ratio instead of the 4:3 in the original. The framework to build it with was also replaced, so it should hopefully work nicely on modern Linux distributions too at whatever resolution you're on.
Sounds like it wasn't entirely easy work though, having to go over each image used by hand to tweak them. Along with that they've used "different high quality upscaling tools" and when they had the original source files those were used to make sure the higher resolutions do actually look better.
It should also be easier to mod it now too, as the assets and save files are no longer encrypted which is nice of them to do. Finally, there's some other graphical and UI improvements included that came with releases to other platforms like the Nintendo Switch.
The newer builds should be available everywhere "in the next few days", with those who purchased direct from 2dboy.com before 2014 getting it first (if you can find your original download link, look it up here).
