I understand that the inventory constraints is an intentional way to make the game harder, but in this game it's worse than usual.
I have 35 inventory slots. 25 of those are items I can't make (sun hats, shovels etc), and it can't be the intention that I should throw those away. That leaves only 10 spots for everything else, which is just way too little. That makes it take an eternity to gain the 1800 gold needed for the arch (which should release the 10 sun hats).
And even if you decide to keep these constraints, please make it possible to discard individual items, not just nothing or the entire bunch. I can see where there is a point to making me choose between throwing away one of three stoves or one of two jeans, but here I must throw away all three stoves or both pair of jeans even if I just want to open one inventory spot.
