This suggestion comes in four semi-unrelated parts.
I think the Jerky and Roast item families should be consolidated into a single item each: a Jerky and a Roast. Having different items for each bug's raw meat makes some sense, if only for realism and lore reasons, but once it becomes food, I don't see any real difference between one and the other. Maybe the Aphid and Tadpole could keep their unique ones, representative of the former being tiny and the latter being large, but what's the difference between a Weevil Roast and a Grub Roast, from a gameplay perspective? Why do I need a stack of 5 Aphid Jerky, a stack of 3 Weevil Jerky, and a stack of 2 Gnat Jerky, all taking up 10% of my inventory, when I could just have one stack of 10 Jerky that does the same job with less fuss?
This one is a minor annoyance and I can understand why it might not happen, but I would love it if the hotbar was a separate inventory space from the main inventory? I'm constantly having to rearrange my carefully-managed inventory because, for example, I equip my hammer from slot 2 of my hotbar to harvest some quartzite, and then when I unequip the hammer, it doesn't go back where it was because that slot freed up when I equipped the axe & is now full of rocks. I like to know where everything is instead of having to spend time searching for something i would've sworn was here somewhere, maybe it's in a chest, (nope it was in my inventory all along but I missed it because it wasn't where I expected and now I've wasted two minutes on boring inventory fiddling instead of actually playing the game), yknow? Make the hotbar a toolbelt, and this problem goes away (mostly, at least), because the tools I'm regularly equipping and unequipping get their own dedicated spots, instead of having to get shuffled around all the time.
I'm sure this one has been said before, but: inventory upgrades? Pretty please? 30 is a respectable amount of slots, but I'd give my whole stash of silk rope for an upgraded backpack with an extra 10 slots! (Also, I'd like to quickly note that suggestion #2 would pretty much solve this problem, because suddenly I'd have 8 inventory slots that weren't used up by my normal tools and weapons!)
Maybe this is already a thing and I just didn't notice, but a sentence in the description of the bow saying "press L to change arrows" or something would be helpful. I honestly didn't initially notice the little thing in the bottom-right corner saying as much, because I'm so used to that bit of UI being largely the same for every tool, so It didn't occur to me to check it when I got the bow. I might be in the minority here, though. I dunno.
Anyway, thanks for your time!!
