1) It's funny; I just saw the recommended play order but followed the exact same one during my playthrough! As for my favorite guy, I'd have to say Reksa by a long shot! Adorable possessive aggressive tsunderes and all. That aside, he was also the most visually appealing for me. I loved his character progression and also the underlying mystery. Then again, bad-boy tsundere appeal and all, I may just be biased. Regardless, I was actually extremely impressed with Rama and his story, Mitra was sweet and while I enjoyed him as well the latter two were just that much more awesome.
2) I play quite a few otome games and visual novels and this one would have been on my playlist one way or the other. I adore the art style and the guys are gorgeous! And I do adore strong female leads. Everything about this game sounded great and playing it was a treat.
3) Choosing one aspect as the best would be difficult, because a good game has a wonderful combination of everything. The game was visually gorgeous and the guys were perfect. The characters would have to be my favorite aspect- ALL of them were so interesting and engaging. The individual character-traits of the guys were so unique and lovable. The story was also interesting- and I adored seeing different sides to the same story and nothing seemed redundant. Reksa was definitely the character to be played last though....
4) Besides Bermuda Triangle, are there any others in progress? I would love to try more of your games! Keep up the great work! I thoroughly enjoyed every moment of it!
