Hello, I absolutely loved Nusantara, so I figured I could answer the questions you left :D
1) Which bachelor you like the most? and why?
I absolutely loved Reksa, I felt that after playing all of the routes, his character was very well-developed and we got to know him extremely well! I also really enjoyed Rama's route, as I felt that he gave a nice contrast to Reksa and Mitra, who were lighter characters( the latter more so). There was a nice balance of the darker and lighter side of Rama, and I loved seeing how his character changed compared to the other routes where he was shown.
2) What makes you consider to play this game?
The art and CGs were a huge part of why I loved this game so much! I find it hard to enjoy a game which has poor art, even if it has a good story. I also felt that you didn't drag on your story, which is a mistake I think people make during the writing process. But your art was definitely what caught my eye!
3) Overall, what do you think about this visual novel? and what element stands out the most? (art? story? character?)
I absolutely loved Nusantara in general! I think a large stand out were the characters personally. I loved the contrast between character, I felt that the characters got more comfortable around Tamara as the story progressed, which gave it a very realistic sense. While the art caught my eye at first, the depth of the characters hooked me on the game and made me want to play it more and more! I also really enjoyed how there were certain things that we only found out in some routes (Such as Tamara's past was not revealed as in depth during Reksa's route). It gave me an incentive to play through all of the routes even more so.
4) Do you have any question or constructive critiques?
While there were some minor issues (such as the music bugs), I think this was very well done! As I'm sure other comments have addressed, there were some minor story errors. I found some issues with the the labeling of names when a character was talking, as I found multiple errors of that (during Reksa's and Rama's routes mostly). I also had an issue with the Q. Saves/Q. Loads, as the game would crash whenever I tried to use them. I did occasionally find the music not quite fitting, but I think that will changed depending on the story, and it didn't end up majorly effecting the playthroughs anyway (Tho I enjoyed it xD).
5) Last but not least, if I make another visual novel, will you consider buying it? via patreon or kickstarter that is.
ABSOLUTELY! I love your artwork, your style is admirable and your dedication and passion towards your characters clearly shows in your writing! I would buy it in a heartbeat!
But in general, I really hope you make another game! Would LOVE to see more of your work!
