Big corporations can't produce art that well. There are too many moving cogs, too many people wanting to change it, and the main drive is always profit.
I'm just one guy, and like most artists, I'm mainly happy that my work is being seen and appreciated! It also really helps that people here financially support me so I'm able to give this project my all.
I'm not sure when HH will be finished, but I can estimate that the main story is about 65% done.
