The new version is much easier, mostly due to the sword being much better. It seemed that before your success depended a lot on if you could find more guns and enough ammo to not run out, but now it's much easier to use the sword and conserve ammo. I didn't find how to save, so that still made it reasonably challenging, especially with the deadly pits. Weakest point now would be the AI and how easy it is to abuse their detection area and pick them one by one. Overall not bad considering it's free.
