This game is really cool so far! What I would suggest is the ability to make your shop better. As an example, your shop could start out with dirt floors and a small, not as nice area. Like a makeshift forge, and a dingy counter and shelves. I think it would be great if you could, for example, change your dirt floor to wood, along with expanding the shop, making a better forge, a better counter, and more and nicer shelves. I also think it would be cool if you could go into a grid mode and put shelves where you want. I generally think customization will be a good addition. (given that the customization isn't too hard to do) And, with moving shelves, (and possibly other things) you could switch between modes of it snapping into place, and when you can move it freely. I think that it should be pretty expensive for any upgrades in the shop, to make each upgrade seem more significant. With the floors, it would be cool to have different types of wood, (like oak, birch, and mahogany) and different types of stone floor options. (granite, cobblestone, etc.)
These are a few of my ideas, thanks for reading them 🙂
P.S. I also think it would be cool to have events going on outside your shop, like two "people" getting into a fight, and having the "people" interact with each other. It would be awesome to be able to move your shop to different locations, like in the mountains or the forest. It would also be cool to have multiple races, like elves and dwarves (races might not work well) One final idea is to add wildlife that you could see going by your shop, or interacting with other A.I.
Thanks again 🙃
