I had no idea what I was doing 😁
It seemd to me that clicking the left grid (4x4) moves my ship according to what it says on the tile (i.e. down, left, nut).
That would control the ship on the larger grid.
But I saw no way to water those plants on the right, I just sowed some seeds and move the ship around. Not sure how to satisfy any of the captain's needs 🤷🏻♂️
Idea seems to have potential, as far as I can understand it, but I wasn't able to decypher it.
