Ugh so there are some problems with the balancing so I won't really bog you down with multiple sections and will just write one long one. The problem with this game seams to be that you have by large no way to gain resources in any other way than the battery and with every item costing more to buy then to sell you end up creating a negative feedback loop where trading makes you lose resources 90% of the time. Now there is the battery that is from what I understand the only thing that actually can give you resources, so we are just playing the lottery with if a customer will come around and sell us one, but then again "can" there is a good chance that in a simullar way to how the player can sometimes not be able to afford another battery from the get go he can also lose resources by buying a battery. So am I just supposed to stay put and just eat what I've got untill I die from not getting anything new. So probably it would be a good idea to at least make trading items an actuall vaiable option where the customers items are less valuble or make some sort of haggling system where you'll be able to bring the price down couse as it stands now you are passivly and activly losing resources with gambling being the only way to make up the losses at least a bit.
