The launcher is meant for changing special .ini files for graphical settings and more work is continuing on the backend to make updating easier in the future.
The game (and the launcher) are currently in Pre-Alpha--systems are still being developed are still subject to change. Once more of the AI and time-compression bugs are worked out, there will be an Alpha release for general feedback and gameplay testing most likely early in 2021
Latest builds of the game are being published regularly, which allow for complete packages to be sampled and debugged locally avoiding any intermediate services and communication issues. These builds are not publicly-available, but you can read the notes here to see the development progress at a granular level.
