Just found this game and played through it starting with Corth, then did it all again going to Tollorix first. Great use of branching to add flavor while ending up at the same place. Exploring the ghost ship was really cool.
The use of the conversation choices to add personality to MC works really well. I was actually surprised to have El remark on it in my two playthroughs. In one, I was going with mostly nice choices, second was mostly funny and she picked up on it. The humor one will probably be where I focus in the future, the jokes in this game are on point.
And of course... The animations. Not only are they really good, I love the use of them to establish relationships between the characters. And the voice acting is good. The MC reminds me of a slightly more subtle version of the captain in Subverse, he's a funny dude.
