It's so interesting that it seems other people got a sense of coziness from this game. I guess it could be a cozy cycle to get into, but from wandering around, gathering supplies and listening to the howling wind I felt a distinct sense of isolation and hopelessness. The subtext of "What brought humanity to this point?" and the other tanks around really made it feel like a hopeless world that you are trying to give hope back to. It's really a beautiful feeling to capture in a game.
Related, I really like the sense of melancholy created from just being a lone little tank shining its headlight in a fully dark world. The green lines from the topology scanner kind of dampen that immersion though, maybe try making that a ping as well? Could even make it a direct upgrade for the main scanner, and just have them both ping on F
