I've uploaded a pre-release build of Alpha 27 for all three platforms. I invite all seasoned players to take a look and post their feedback in this thread or in the comments below.
Please don't opt in if you are new to the game, as this build is very unstable, and the tutorial doesn't work at the moment.
To opt-in into the build, please go into the game's properties, BETA tab, and choose the "dev" branch.
