By 'cog counter' I mean like 0/4 so you know you need to collect them and how many are there. They catch the eye on the minimap, but at first I only saw one, the others were a little overshadowed by minerals. I was thinking they would serve to update the rover, like the last update or something. Only at the end did I understand that they were used to fix the ship and get off the moon. But that would just be a small indicator for the player, the game is already great the way it is. :)
