the best deselect button layout ive seen is diselect on right click. usually deleting structures has a button or option somewhere on screen. im used to being able to deselect or exit out of something with right click but im not sure if thats just me. i play alot of city management games like this and thats a common feature,
ill deff follow on itch.io but unless your on reddit i dont really do social media so i dont got any accounts on anything lol unless your on youtube
