Now that I've played all three routes I shall answer the questions. hehe
1) I LOVED RAMA. Which is why it breaks my heart when I saw his bad ending or anything bad happening to him. Why do I love him so much? Well, he has a lot of similarities with me. It is sad but I can understand his pain so perfectly. T_T Yes he is a tough rock to crack but once you crack that rock, you'll find the purest diamond inside. That is Rama <3 He deserves nothing but love. I'd literally kill for him. I'd do anything to protect him. He's perfect.
Mitra would be second. He is like an angel. I love his positivity and innocent nature. He seems like the type of guy mothers eveywhere would want their daughters to marry. lol but I do not think he would understand the the darkness in my soul. O_O
Reksa is awesome. His story was really nice. He has a great personality and evrything but the depth of Rama's character and the way you get to see his soul opened out to you like that, that overshadows everyone else. Rama's route was the only route that made my heart beat go irregular irl. <3
2) I play a lot of otome games. I chose this one because it seemed so interesting. I love the tribal concept of it. The art was very beautiful and different from other novels. The story was fantastic.
3) The best element would be the writing. The art needs a bit of touch up but its still very very good! I would love more flirty scenes with the characters but the story is still brilliant without too many of those, so dont worry about it. I am a huge fan of your work now.
4) I do have one suggestion. Can you do some more Rama drawings? <3 If not, that is fine but my heart longs for them. lol. ^_^
