I like the concept of this game, and the art looks very nice. I think some feedback on the tumble weed throw would improve the game. Also, some feedback from the mouse when it's hit. I like the idea of getting water and shading yourself. Also, it's good that you have to get to the oasis. If you wanted to expand the game, I think you could add another enemy with a different movement set. Also, some terrain that you have to navigate, although the endless dunes works thematically. :)
