We have some exciting news for you all. First of all, we have made the game soundtrack publicly available as a steam soundtrack. This should be accessible from the store page. These are all songs included in the base game, but just bundled differently for easier listening.
Next, as we work hard on the new 0.8.0 version with a lot of changes, we have automated the entire system so that now betas and nightly builds are available on steam! You will have to right click on the game in your library and opt-in to either the beta or the nightly. The beta will consist of the latest manually tagged beta release, while the nightly is built every night using the latest source code! Due to this, expect to find bugs and issues in both. That said, we would love to hear about the issues you encounter and thoughts about some of the new mechanics.
If you try either the beta or the nightly and find any issues, please report them at the issue tracker. Discussion about the game can also be had on Discord (discord invite).
