I have to say, the game is very interesting, since it's not the usual dad is dead lets fuck everyone game. It is unfortunately very sandboxy, and that means you'll spend a lot of time clicking through stations for the random first encounters, not something a lot of people will like.
There also might be a problem with the events trigger? Like I had a message to meet laurene at uguisudani at 2pm, I got there, waited 10 mins, got no event to pop up for it.
So with 24 hours timer, with only 15min time skip(it's actually 20 min time skip but listed as 15) or ride the subway back and forth to kill time, and very limited meeting times with the girls, you'll be spending a lot of time clicking - Take a walk (spend time 15mins(actually 20)). Maybe have the option for bigger time skips?
Eventually laurene triggered at 1:54am as I arrived at the station, it played out like it was during the day at 2pm, and then back out of it the time was 5am lol.
Also maybe show money all the time or in the backpack, the times with chizuka I couldn't tell if I had money to pay for her, eventually I saw I had $47k to spend.... after she tried the blackmail stuff for 5 and 10k after I tried to get out of paying...
Just needs more scenes and random events to chew up the time, rather than clicking through random stations.
