I feel a little silly asking this- but I am horribly stuck trying to plant the first 3 seeds.  I'm stuck on the very first whalehex area.

I will fully admit this is likely a user error, but I'm not sure where I need to be dragging the seeds too in order to modify or plant them.

Dragging, and both L and R clicking in the inventory doesn't do anything, and same with click on the 'holes' with matching #tags.

I would love a gentle explanation- I really want to progress in this lovely game! The visuals are incredibly unique!

From the dark inner shore area where you created your seeds you need to make your way to the right. There is a pod there where you can sleep to advance the day, you'll awake in  your cabin which exits to your farm on the right. There you can plant your seeds, but you'll need to plow a red whaleskin tilee first by selecting your tool with (2), then holding (LMouse) on a nearby tile. Happy seeding, the next update will prioritize creating a better new player experience to make this all more clear. The game is still very unintuitive in many regards, sry.
