I couldn't agree more with the reviews that have been write before mine. It's a hard game, but it gets almost to an insane difficulty level after a couple of days. I've died dozen of times on just day 4 because there are no supplies to be found ANYWHERE. The total random generation of the levels is cool, but it does not help that there's no consistency in the supplies-place. As said before, it would be more logical to find a lot of food or at least some food in a store. In a house you would find some ammo or gun more often, and this is kicking in an opened door; a gunshop should hold some guns... But nope, there's non of those.
It also doesn't help that most of the street levels have cars in them... that just can't be reached. Annoying. And yes; a GO-> would help, instead of forced moving to the next screen. It helps that you can focus 100% on the killing of the big mamma's and fat bastards, and than later sweep the area clean of all drops.
Besides, how does the EXP work. You only get EXP when killing, which is weird, since you might as wel "learn and gain" while crafting new guns or farming. Right?
Anyways, I've tried a good amount of times to see if i can get any further than just the one time I reached day 15. But I didn't get past 10 later on, because of that low supply drop "bug" I just call it. Besides, a merchant; cant he sell those wood, duct-tape, batteries or metal bars? Might as well have'm sell those too, instead of just the regular weapons and armors.
But I'm repeating all those others now, so this was it.
It's still a pretty addictive game, if you're willing to look past the brutal difficulty..
