about the selection issue: stardew valley has the same guide system, but the big difference is that you can use your mouse cursor to hover over the 9 tiles around you, and that'll update the guide so that when you click you'll target that tile (and automatically face the right direction). this makes it a lot easier to do things like stand in one place and water a bunch of adjacent crops without having to wiggle around each time to align perfectly.
something i'd suggest would be to expose keybindings; as somebody who's left-handed WSAD controls are actually really difficult to use and it would be great to be able to change that to arrow keys.
