The game is fun, with nice rogue-like concept.
However, it is a shame that the game is too difficult. I have seen that there are more areas aside from the desert, such as the mines and the snow area to the north, but in my best run I accumulated 5 gold, and the cheapest upgrade is 50 gold. I am not saying that the game is impossible, but the difficulty needs a bit of tuning, and it is a shame that the difficulty prevents players from exploring more of the game
