A lot of people have already said some of the things I've noticed (events cancelling auto-spiral in dialogue, spiral lags toward the center with slow spiral + auto-click (could be a pc issue), etc.).
One thing I'd suggest is labeling the quest/session switch in the tists menu. I thought it was a progress bar since it was under the tist progression and I thought the induction stuff Faust mentioned hadn't been implemented (and I was a bit out of it from staring at a spiral, haha). I didn't realize there were actually inductions until after I finished all of Faust's quests. Because of this I sequence broke, in a way - I bought the crystal and got my King's introduction, and later on Faust told me about the crystal + naga she saw around the lab.
The last thing I'd suggest is telling the user the button commands (fullscreen and "go back") first. I accidentally skipped a text box while navigating menus during the tutorial.
Despite the issues I and others have stated, I really enjoyed the experience. I look forward to future updates. :)
