This is a very well polished and thought out experience.
Creating a puzzle game like this is always impressive because balancing can be really difficult. It took me awhile but I was able to hit 33 tiles on my last play through, it never felt completely impossible and being able to see your deck in advance really helps strategize.
Perfectly adheres to the journey theme as it brings across a feeling of exploration.
Honestly can't think of too much to criticize, I think it would help to add a marker to where you are currently, as sometimes I would go deep into thought looking at my deck and hand then back at the screen and forgot exactly which tile I was on until I clicked on a card to open the movement selection. Maybe a little explorer guy or something as that would help thematically(since this kinda has the vibe of Civ where when you are sending a scout out.)
It didn't happen often but sometimes I strayed too far up and it was hard for me to see the tiles below, so being able to move the map would be useful when someone wants to plan a route.
Overall this has been the stand out of the Jam so far, nice work.
