I think I first downloaded this maybe a year or so ago, and I've been thinking of it every once in a while. I figured I'd comment since no one else has yet: I am a big fan of this. The whole low-poly, limited color palette look works really well and gives it an interesting style, and the lighting/shadows in particular are my favorite part. The effect of the flares are great but the smaller touches are nice too, like how even activating the radio gives off a small pool of light. It all helps sell the dark but somehow almost comfy atmosphere that this game gives off. The sounds of wind howling as you tromp your way through the wilderness and into the void.
I love everything about the mech too, of course. The design reminds me of a cross between an AT-ST and an AT-PT from Star Wars, mainly because of the legs and way the body is positioned. The slightly awkward walking animation combined with how lanky the legs are really give a great sense for how clunky (endearing) the mech is, and how if you did someone find something in the darkness you probably wouldn't be able to put up much of a fight. Or at least, you'd have a tough time running away from anything.
I know that you'll probably never update this considering how long it's been since this was last updated, but I'd be super interested in seeing this as an actually fleshed out game. The bones are certainly there, anyways. Considering how many walking simulators there are out there, it's a shame that there aren't more with non-human player characters. Having a mech game where combat isn't the main feature could certainly be an interesting angle.
I'd love to see this be continued, but as it stands it's still a weirdly cozy little game that I enjoyed quite a bit, thanks for making it.
