I've only finished Kien's route, but I'm buying 3 copies on steam for 3 of my VN friends, I hope it starts doing better because it is definitely my favorite game of yours so far, and I LOVED TROS.
I still need to write up my full review for you guys, but I need to finish Tai's route (which I'm currently playing this weekend) and then the last one. I have so much to say about it. I'll make sure to buy a copy for myself on steam too so I can leave a review there as well.
