I loaded the game here a couple months ago and I couldn't start it. Now I found the source code on another website. Using Godot 3.5.3 I was able to create a usable version for my 32 bit Linux system. The game looks high quality and professionally made. The game will be my pastime for the next days.
thank you ! https://github.com/HarmonyHoney/ROTA i hope you are getting the source from github ! what did you change to get it running ?
