I'm still a little worried. It seemed a litte abrupt, his twitter has also been completely dormant since. He uploaded the last supporter demo for everyone for free, something that seems like a mistake but he never corrected; felt to me like a "throwing in the towel" move but I shouldn't be alarmist. We'll just have to wait and see.
I think his redesign of the MC also got rejected by Steam or Dlsite which still deem her a "minor coded school girl" or whatever and the payment processor stuff was also still a hot topic around the time he took his break, feels to me like these things are related.
Keep in mind this is just my observations based on me following this game and reading the occasional auto-translated post. Someone else might have a better grasp on the situation. Either way, better to give him time and space.
