He's right GRUB HIDE is a bit much, can you give us Insect leather instead of forcing THAT particular bug? (Or ok, don't add a new item this late in the game just let us throw insect parts of any variety into the grinder and get leather scraps, easy, that would even let us trigger payback events more frequently and lead to a better gameplay loop while we farm) Many of the same bugs drop acid glands and I'm easily sitting on 230 of those by accident, why shouldn't the first level be this easily accessible. Quartzite for the weapon can be found everywhere so should level 1 upgrade. Berry and pupae I'm fine with the costs of since you can exponentially speed up quantity for time with enough buildings.
Also he's right about the canteen, if you want to add durability for it that's fine, go ahead, can you make that durability only trigger on picking up dirty water and NOT Dew Juice Soda. Breaking the canteen filter shouldn't remove its functionality either, if the filter doesn't work the container still does.
