is all 0.6 added just the gloryhole and clues 1/2?
Yes it is. I understand game development and writing are tricky. And likely organizing a recording date with the voice actresses take a lot. It is likely a passion project more than anything. But... being honest here, this is way too little content for a 2 month (ish) long wait. Maybe give it more time between releases or... something. But I am disappointed by how little there is here.
I think this was a 4 week update. Itch is 1 update behind. Here's the devlog of the new changes:
