Alley_Cat, Bibifoc
As a non-English speaker, I sympathize with both of them.
I started with my save file and was flustered when I saw the one-minute empty space.
Second, when I started again from the first page of Part 2, I succeeded in triggering, but I had another problem. (I won't say it)
When I restarted for the third time, I watched Walkthrough for the first time and followed it as it was, but I had another problem.(I won't say this either)
Eventually I used the cheat key and succeeded in clearing.
However, there is a section where problems occur even if I follow a walkthrough or use a cheat key.
What I felt while playing was that something was twisted and after this story (not the next update) LP seems to need a fix.
