Struggling to make money!


I think this is an example of something that varies depending on play style. I quite often leave my backpack upgrade until late spring, to allow me to invest in other things. It is fine if you are organised with chests in various locations.
I think the backpack is most useful if you like to go into the mines a lot.


I think bringing a chest with you and placing it over by the minecart mitigates most of that, you can drop off rare finds every five levels.
I agree - I mine a lot in the early game, in order to make quality sprinklers on spring 16 for my fields full of strawberries. I normally do that without the backpack upgrade, because it is the price of 20 strawberry seeds... But the chest at the top of the elevator means I throw very little away when mining, and nothing that I regret.
