I seem to be in a similar position. My levels are 19, 16 and 16, and I only had 5 active skills for a long while, but just unlocked a 6th (I have no idea how). I have no passive skills. I've only seen the 3 option thing one time, chose the first one and it was instantly game over. The percentages and markers for which areas are safe don't seem like they're working correctly. I've also experienced a hang where it looked like one of the non-controlled characters just kept trying to move through the crowd on the train, and I never got an option to do anything - had to restart. For progress up to this point, I seem to have had the most success by sticking with 1 girl at a time in the left-most train car. The girls with dark blue hair, purple hair and blond hair are all easy to advance. However, I have not made much progress as with the girl with light blue hair - whatever I try seems to fail right away. On the middle train car, the girl with brown hair wearing biker shorts/swimsuit, and the girl in white with black hair are relatively easy to advance. There's also a girl with green hair that seems to ride in both the left and middle train car who isn't too hard to advance. I have not made much progress with the girl with read hair or the girl with dark blue hair in the blue outfit. Similar to the one girl in the left car, whatever I try with them seems to fail right away.
Could really use a translation for this, especially the skills to figure out which ones are useful.
