I guess don't make the game required to have a mouse. As like mining requires you to hold the right click or having to right click for fueling but I think this could be easily taken care of with a config menu. Also playing a bit more it would be nice having a way to copy/paste and delte/move an area of objects to not have to click individually to mitiagte the time it takes to make a building or putting it in the trash bin. Then there was also the drones (can't remember there name) where it seemed like that the can only drag and place one location at all for the item itself. Lastly, I was trying to make an automation but I was stuck on finding out if it was possible to put fuel in the drills. Was I doing something wrong or is that not possible in the game yet?
The game was designed with mouse in mind, so would take a lot of rewriting to make it possible to configure the click buttons to keyboard buttons, and I don't think it is worth it, as most people have a mouse even for laptop. I have considered copy paste, but I don't think I am good enough at programming to make it work. The drones usually have one position from which they pick up and one position to which they deliver, and a range of 96px I think, so if a position is more than 96px (radius) away from the base, it won't use that position. It is possible to put fuel in the drills, both by hand (right click) and with funnels/drones. It could be if the hitbox of the ore vein is in the way, that the funnel won't be able to be placed right up against the drill, in which case it won't funnel into it. You can fix this by placing the drill centered on the ore vein, or off to one side where the funnels are gonna be.
