You need more years to actually be capable of winning. Besides that, you should have the goal of saving only 1 city: the rest can be saved for bonus points.
Ffs, what am I fighting? Elite stuff? I expect small dungeons to contain level 1 monsters, not instakill on entry. (I actually managed to die by clicking the "enter small dungeon" button.)
The diablo concept might be considered stolen. However, once it's branded as "fanwork" (Which it is), then it's rather weird to call it a stolen concept.
How could the saves be crappy?
It has normal saves, auto-saves, and a savefile restorer if you screw up. It even works if you think 5 minutes later "Oh wait..."
I mean, when I break my bat, I lose my skill point for that round.
... Which means I'm going to be in trouble for the next one. And because of that, for the next one too. It's an annoying paradox where you go game over once you failed once.
