I have only had a few hours play time but I am thoroughly enjoying the new "no jars" change making the early game a lot more challenging for me. In a20 And most alphas prior, water was just.. obviously too abundant, so I feel like this is a positive change even though it may not feel as "realistic", the change makes the survival aspect a lot more satisfying in my mind. I have still been able to find enough murky water just from looting things which is good.
I have died twice but only because I am getting used to the slower progression of Food and water accumulation I just had horrible stamina recovery and bit off more than I could chew, so I know I have to hold back from zooming forward a lot more (which I like because I actually have to think about how I should approach things in general).
The loot stage I am at is only dishing out mainly stone tools which is also feeling like a nice balance although by chance I found a orange iron crossbow which was A real feel good find!
The "read books to learn" change is also good although I do miss the "get better by doing system" even though it makes everyone cheese things.
Anyway, I can't wait to play more! a21 is golden, Thanks Pimps.
