The inventory is a bit confusing, due to the separation of the item on top and its actual count shown on the right. The night takes up part of the game time and in the morning you find yourself in the sand (I just bought a pot! And it was lost in the sand!). Grid works well and the game messages are really help! Fill like need button "sell all" or "some count" in the store.
The sand idea is interesting, maybe opportunity to get rid of it would be good (you’re a lonely farmer who’s come to conquer this desert!).
