I am running this on EndeavorOS (Arch Linux) with a GTX 1060 (6GB), a Ryzen 5 3600X and 16GB RAM.
Found a bug in the main menu. I clicked on "New Game", then on "Cancel". It brought me back to the main menu, but the "New Game" menu was still open under the main menu.
Some entities have weird colors. I can't tell if this is intentional. I haven't played since 0.2.0. I apologize for my ignorance.
The structures don't seem to slow down my machine.
Yet, when I go "outwards", the game does slow down for a couple seconds after some distance.
If I find more things, I will let you know.
Keep your smile.
