The way the controls work in Stonehearth is simple and beautiful. I do have a single complaint, though: the left mouse button is used both to move the camera and select items (like beds or fences). This isn’t the heart of the problem, though.
The problem is that to unselect an item, you click on the world or on something else. This makes it impossible to pan the camera when you want to, for instance, place a bed.
There are multiple ways to solve this problem. My suggestion is to make panning the camera use the middle mouse button (but this would be problematic for people using a trackpad or without any scroll wheel) (also, middle mouse button seems to make more sense if it rotates, and the right mouse button panning, but that’s not the important part). Another way is to make you unable to unselect the item if you’re placing it.
These are the two things I’ve thought of, but if you have any other ideas, please reply!
