Overall, it's ok. The monsters get pretty tough though, hard to survive (-1). Navigation is hard, adding to desert theme (+1). Interesting to explore the resources and see what's what and what they do (+1.5). Not the best inventory type (-0.5). Not much variety (-0.5). Good control of character (+0.5).
Some ideas could be to tone down how strong monsters are from when you start, so players have a better idea of how to survive. Also, more objects/things should be present. There is a lack of life, and from the crystal ball, there is only 2 plant types and some ore. Knowing it's not going to be updated, I shouldn't judge down for some things (+0.5). You should work on this game and you could change it. Get rid of what you don't like about it and make your original idea.
