Sorry for a very late reply, to be clear my issue is not that there are people working on the character designs or still in progress. To be clear the crux of the issue is the first link you posted imo. This line in particular.
"Modeling and design are in progress in parallel with Ver0.2.0, but we won't be able to start making Ver0.3.0 in earnest until after Ver0.2.0 is finished......."
Ver0.2.0 feels and has felt completed for a while. We are continuing to get scenes for Herba and Alice which aren't quite progression but nice to have. I'm not quite certain what Ver0.2.0 is waiting on or more specifically what the goal that needs to be achieved for it to be finished so they can "work on Ver0.3.0 in earnest".
To be honest I would rather have Numeric Gazer put in some modeling work to make a nice side enemy to make alongside the other modelers to then start working on scenes for, rather than Alice or Herba. Not because I dislike them, but because I don't think its wise for Herba and Alice to get 8-15 scenes and then expect every future encounter to have that many. Herba might be excused because she will be a persistent shop keep but Alice less so.
TL;DR this is a rpg about fighting witches (and lewd scenes when we lose to said witches) I would like to be doing that, not just sparring against are "ally".
