The music was calming and fits with the chilling aspect of the game. Love the fact that there's a guy who follows you around and play it for you, too. The game doesn't feel tedious to traverse, and gives the player all the info they need, which is a really good thing for a jam game where people just like quick simple stuff. The fact that you made a working game with procedural generation in such a short amount of time is a really pleasant surprise in a jam like this.
1. I feel like the world is too barren. I know that it's supposed to be a desert, but I still think there could be more stuff in it. Maybe the cacti could be more spread out, more structures here and there, things appearing along the river, etc.
2. Right now, there isn't much of "game". In a way that you can't really fail or learn to do better. It all comes down just to a shortest path algorithm to achieve the shortest time. I know that might be the point of the game, to chill, but I feel like there could be much more to explore. For example, maybe it could become an economics game, a game about merchants, maintaining the happiness of the citizens in a more complex way, etc. I know that this might seem like I want you to change the point of the game completely, but I do feel like this is kind of a tech demo of a much better experience.
3. With a more consistent art style, I would've liked the game much more. Right now, it look kind of weird that you combined the blocky and smooth terrains to make the world. I would've liked a blocky voxel game more for example.
Sorry if this comment come across as negative overall, but believe me when I say I really enjoyed it. Many of my criticisms may have sounded nitpicky, seemed unreasonable for a jam, and are just my opinions. However, I do want to see the game improve, if you ever wish it. It seems that you've poured a lot of hard work into the game, and I could really feel it.
Good luck with the jam!
Edit: Forgot to mention that the sensitivity was extra high for me.
