Well I think I hit a point where I can't continue without using IAP. I need to complete the merchant guild mission (collect 40 glittering stone). But I have to have 6 tables to sell in the industrial district, 1 container to hold supplies, and I'm stuck with my 3 other quest items (Grandfather's box, Fruit Sorting Certificate, and a key for the box) which will take up all 10 of my inventory spots. So I will have no space to collect the stones without buying peaches to expand my inventory.
Kind of stinks I was enjoying the game.
