I have been reading a book on Krita and it looks like I will be using that.
I have a very old copy of Photoshop from 1999 that I may use. I also have Spriter to make animations.
Now I need to live long enough to learn these and decide how I want the game to look.
I think there is a long road ahead.
To answer your first question, I am not quitting, just taking a detour again.
( If you are wondering about the age reference, I am 75 and not in the best physical condition.)
