I try to give tiny updates when asked about it here in the comments, but I'm also very responsive on the Discord server I run for this game (public link available in the game's main menu). I don't necessarily announce progress updates, but I do have a #dev-diary channel when changes are saved to the project files. It doesn't cover everything, as during periods of writing or image generation this channel doesn't get updated until it's all finished and added to the game, but it is a little way to track progress for those who are more interested in that.
Best way for now is to just ask I suppose, whether here or by joining the Discord server and asking there. I got 12 images generated yesterday, so progress is indeed happening just at a much slower pace.
