I currently have no build of Terra Forma for Linux. Sorry.
I am interested in what version of Unity is used or what year this game was created. I may be able to play it using Wine.
It is a 32-bit binary I released around 2014, which I think was still during the Unity 4 time frame.
Then I guess that the game works for me with Wine 1.6.2-20 or 1.8.1. The other problem: I do not use online banking. I buy games from GOG using Paysafecard. I am interested in your game. How does the game get to me?
Regrettably, at this point in time, Terra Forma is only available to purchase on itch.
