The small demo was nothing short of fantastic but, I cant help to wonder if this project has been abandoned, the last update/post was 1-2 years ago despite me finding other projects that may involve this same creator in a different account (Radcowboylad/skellybed).
I don't know anything about coding or how hard it is to move/redo the progress of the game to unreal engine but I am sure that everyone following this project would like an update regarding the progress or if this sim has been cancelled or abandoned.
