A game written entirely in Latin is an interesting concept. I like the idea, but I do wish there was some sort of translation guide available so I could understand what was happening in every conversation. Outside of a couple isolated words that I could catch due to similarities to words in English or Spanish, I had not a clue what anyone was saying. That is partially intentional, of course, but I do thing that game would benefit from a sort of in game glossary. I think that would also help with the sensation of trying to figure out what's happening on this island that you've stranded yourself on.
Still, though, this is a solid and interesting foundation!
