Some points i would agree others not so much. Asfar as seeds go i think its pretty okay as is. Sure real trees would drop alot more but real trees wouldnt grow in a weeks time from seed to full growth so..

Same for fine wood trees, sure it would be nice but then again i do think it encourages going out and look for them. Also it forces players to face scarcity which makes choices obligatory, you cant have your cake and eat it. Having said that, I would like acorns having a 1 in 10 chance to drop tho. I love the visuals of oak tree's and am bummed everytime i chop one down. Would love being able to plant them for their aesthetics but not for harvesting.

Your idea of harvesting corpses i just find weird and very much out of place in this game. Sure do agree the puffy cloud sucks and i hope its just a placeholder, no need for the wait after killing something but harvesting corpses!? Sounds very much way too dark for this game. Increasing resources as your skill grows would pretty much go in the face of your reasoning for the ability to exist. Not until late game, when you argue resources are plentiful anyways, your harvesting skills would be high enough to actually do anything meaning your scarcity early on just remains, if not worstens.

Trophies i fully agree, anything would be great to do with them. They suck and take up inventory space forcing micromanagement of the backpack. Anything will do please!
