When placing buildings, they seemed to not be visible or were rubberbanding throughout the screen.
Another bizarre one also when placing buildings, some buildings would appear at gigantic sizes, though I only experienced this in the later days.
The options menu didn't seem to work.
Oh and since I wanted to but forgot in the initial post, maybe rotating the camera should be simpler keys like the common E and Q.
The new version is up! I wasn't able to reproduce the rubberbanding / invisible buildings over the weekend, but I'll keep trying.
What monitor resolution were you playing at? Was this fullscreen? Sometimes these things matter. (Also, this is my first project using Godot, so I'm still learning its quirks.)
Camera rotation is in! Q + E, A + D, and Left + Right all rotate the camera.
