I only just found this game a few days ago and now I'm almost at the end of the 0.13. I was expecting something decent to pass the time, but then it quickly became one of my favourite VNs. The writing quality is top notch. All the interactions between character(s) feels very natural. Even scenes that I felt was a bit stiff flows smoothly and didn't hurt the overall story. I'm looking forward to the next patch!
p.s. I'm gonna open with I will always respect your creative direction/decision and will enjoy your work no matter what. With that out of the way, here's my 2 cents:
Samantha (as of 0.13) could totally fit in with the Main casts instead of a Side casts. Eventually, anyway.
