Seriously, don't donate to the patreon then. If the pace bothers you, don't support the dev. If you are getting the game for free amy way, well, you're complaints are gonna fall on deaf ears. That being said, from everything I've read the artwork and writing are the smallest portion of the work involved in rpgmaker. Bo Wei himself said its only about 1/6 of the overall work, with the actual programming being the real time consuming aspect. Drawing a manga doesn't exactly compare in terms of speed. Drawing six mangas does. Dunno if any of that is true, I'm not a programmer or dev, but I bet someone on here is and can verify.
