Patch difference from last build (0.55m) is 373mb.
Our plan is to make this the second last update before our full world update. The next playable update will add a little more world, then we will release the full world to all players.
If you backed through the Humble Store, you can simply download the newest version via your widget purchase reward content.
If you are a Kickstarter backer with a Steam beta-unlock key, please make sure you opt into the correct beta for your platform (Note that for now the build is WINDOWS ONLY due to compute shaders no longer being properly supported on Linux/Mac platforms. We're still working on a fix, which should hopefully be available within the month)
You can do this by right clicking Koe (声) in your Steam library, selecting "Properties", clicking on the Betas tab and opting into one of three beta builds, select the correct one for your operating system. The default beta ("beta - ") is Windows.
