This dev also abandoned his previous game. Why does he think people will have any kind of trust he's gonna finish his next planned game when there's a pattern to his projects? That next game will likely end up abandoned as well. He started up good, but lost the idea how to move the plot and develop the scenarios with main and potential side characters. If he ever start another project i'm not gonna touch it unless it's finished and the next one will be probably be abandoned after few releases.
Hm. I don't think that my work was slavery or something like this.
I make free games to my own and players joy.
When project lost to me - i abandon it. Don't try to play with milking donation or just vanish.
Yeah, it's not cool to start something and then leave it, but still i have my reason to do so.
As player you can judge me as you want, but still try to think of me as a person and ask youself - how are you will do same situation? And if you think that game development is easy - nope, it's don't. Overwise everyone do this.
Still i like to make something for others, so my work will continues, but maybe not the straight path.
