Can you list out what other things you hope to get done with time?
Yeah sure :)
Redraw sprites of locomotives and wagons.
I would like to add a brake effect, but I don’t know if the game engine will allow it, since a similar situation happened when trying to add a warning sound effect.
I would also like to add agricultural wagons and battery wagons.
In general, these are the main tasks that I would like to implement to begin with. Maybe after them there will be some more :)
