1. Why is it even allowed to sell basic materials (water, wood, stone, tools q0) on the market above the NPC prices? I can't see how it could be useful to someone honest, and it can only hurt newbies who haven't realized that nobody will ever buy their goods, and yet have paid the 10% commission on these goods. I would suggest to limit the price you can set at the NPC prices (and that could probably be done for contracts on these goods as well).
2. About the fruits - why are there so many different kinds, and only grapes seem to have a specific use (wine)? Have I missed something (I'm still only a Freeman), are there other plans which have not been implemented yet? I have the feeling that they could at least have slightly different requirements (in terms of water / cost / production time).
3. In the balance sheet, it would be convenient to have an additional column for the previous day, especially when you want to check the numbers just after midnight and all the data has been set up to 0. Ideally, you could even check any past day, but I suppose that requires too much (mostly useless) data storage - but maybe as a premium account benefit?
4. (a minor bug report) When you upgrade a building, what is displayed in the buildings list is different depending on the building type. For research buildings, the final building size is not displayed, and for workshops and stalls, it is displayed, but in 2 different ways (I don't have any upgrades running at the moment so I cannot check exactly, sorry). Definitely not a big deal.
That's it for now - I should have noted down the few more ideas I had earlier and cannot remember at the moment. Maybe later.
And anyway, thanks for a great game
