Really fun game!! If you're taking suggestions, I have a few:
1. A toggleable minimap showing the layout, current position, and the position of your mining robots and lasers. Also, a keybind that opens the entire map up. (With fog of war, of course)
2. A drone facility that basically zooms your screen out when interacted with and lets you look around the areas you've already cleared. While in this mode, you can spend 100 electronics and scrap to move laser towers from one point to the other (when you select it and then move it elsewhere, a little "Amazon drone" shows up, snatches it, and plops it down on the other spot). Moving the towers around is a chore once you've cleared out much of the base.
3. A bomb storage which increases your max bomb cap by 2 per storage built
4. Bomb drone. A drone that moves along the layout's perimeter and stops once it reaches a tile that needs a bomb to be destroyed. It stays there and attempts to use a bomb off the player's storage. If it succeeds, the bomb is planted, and once it sees no more bombable tiles adjacent to it, it proceeds to move along the perimeter again to repeat the process. If there are no bombs in storage, it sits at that spot, waiting until there's an available bomb. (Suggesting this bc a lot of times my bombs sat at the maximum value, 5, and this way, they can be used more efficiently while automating the process)
5. Make it so you can scrap laser towers.
