If you like NetHack games, you will love this one. I played this game during the times it had the name "Falcon Eye" when it used to come on Linux. The game is very simple but very addictive. It is quite hard as well, if we die, we lose all our progress. It is like a DnD game, all it's a matter of luck and odds. We need to manage our inventory and survive the trials that await us (including also hunger, our character gets hungry too). There are many classes and some races. This game is pretty good for killing time, but it is stressful when we have a good advance with a high level and end up in very dire situations.
