Trying out on PC this time, and it seems that bugs got worse?..
Apologies to be the bearer of bad news again.
Just in case anyone else might read, SPOILERS.
So what I've encountered on 1.02 so far:
- PC/Phone: The "keep holding to skip" in the ending section doesn't seem to work.
- PC: 
This is the regular achievement screen. In stats screen it says "achievements 3/5". I've checked the shadow achievements, and they stated that I have 2/5, so it might not be connected, as I assumed it would be at first.
- PC/Phone: Once you get a certain rhythm going, the whole "plap cooldown" when you let go of holding/button just doesn't appear. You can pretty much just spam click.
- PC/Maybe Phone too?: I've counted - I did 10 perfects in a row during zuri, but the shadow achievement still isn't listed as unlocked. Pretty sure I also did the 10 of everything (unless it has to be specifically 10 and not more, like in Kuraksa's Room), it's not unlocked.
- PC/Phone: Still don't know what causes it, but stat screen at some point just disappears, until you redo the ending sequence.
Maybe a full save as a possible download would be good? I do want to see the things I've not yet encountered, but with mishaps of this kind it's a bit difficult TvT
Still wondering how to encounter the "black eyes" someone (Kuraksa, I assume). Pixel hunted everything I could think of, tried to type in the names Sonia, Lucy, Deolia and Diaole, and even tried drawing a pentagram on the altar, heh.
As always, thank you for your hard work!
