Hello. Sorry it took me so long to respond, I was sick. The idea is that the player separately develops on his planet, installs drills for the extraction of RBNs and solar panels for the extraction of energy, which is needed for the drills and for the turrets. Turrets are replenished with ammo through time and energy. In fact, I took the idea for the game from the java game Islands Missle Invasion. But since I made all this almost on the last day, I didn’t have much time. (I even wanted to make multiplayer with websockets lol) :)
