Hey, did you post something in the Discord about this? It's strange that I've had a few people talk about it recently, otherwise.
So asea, in the context that the MC uses, he's asking if they're at sea.
Admittedly, it's a strange word to see written, lol.
Edit: However, there will likely be more than a few grammatical errors in the game. If you find any more, feel free to post them here and I'll take a look at them.
