Cool concept, I really enjoyed the mechanic. One thing I think would help is if the the ground had more variation to it, sometimes it didn’t feel like I was moving because it was just a big solid patch of green. And to make it even better, dividing it into sections with landmarks. Not necessarily literal sections (though that would work), but maybe the top left is a forest, the top right has a lake, bottom left has lots of rocks and the bottom right is mostly grass. With these landmarks, it’s much easier to make sense of where the player is.
Obviously you could do other things, like an indicator of the player direction but I actually think what you have is more fun and engaging. Keep it up!
