I have recently switched to Xubuntu 16.04 and would like to attempt to run my legally owned copy of Blockland with Steam authentication, if possible, as opposed to buying another key and playing it with a non-Steam client. I have thought of clicking the "CD Key" link on the side of the window to acquire the key I had before switching it over to my Steam account,
but have found, much to my disappointment, that the said option does not display. I have also taken the liberty of using
this script to manually create an app-manifest to force Steam to install Blockland (it wouldn't do so under normal circumstances and I would get an
error like this every time), and yet I have found, similarly frustratingly,
that the .exe files were not installed with it.
If I could either run it under Steam normally (as is preferred) or acquire the original key before the Steam switch-over, I would be very much appreciative.
Thank you.
