Yay!  Helionaut actually worked for me on Linux after a fair bit of fiddling.

I had to do a few things:

1.  install d3dcompiler using winetricks (winetricks d3dcompiler)
2. i ran it via lutris to apply the following settings:
3. disable dxvk ("runner options" tab)
4. enable windowed/virtual desktop (same tab)

With that, the game ran for me and was fun!  Until I lost my home planet. :/  Damn.  Now I got to find it again.

Thanks for Helionaut, it's really nice!
