When it's "ready™".
It's being developed for Windows PC first and foremost. Other OSs will follow, as soon as I can test the builds.
Console releases are highly unlikely at this time.
Because I'm not a composer. Not a decent one anyway.
More info about this will be released later.
Most of the challenges I tackled when developing the game are (or will be) explained in the #gamedev news category.
If something's really troubling you drop me a DM on my personal twitter.
That's not really a question, but you can drop a couple of lines in the official discord server.
That way I can ask you more info if the bug is hard to fix.
