The sounds were also quite nice. Combined with how little you can see, I think it plays well into the player's imagination of what could be out there. In a way, you make the player scare themselves. Pretty neat trick.
The last segment when the player gets to the bottom was a bit lacking, however. It's just a big red box. It would've been nice to see something there. With that being said, it was creepy to have it suddenly jump to the android with the baby face on it. For some reason the face reminds me of the guy from "Discover My Body".
I also wish there was more on the scavenging side. I kinda get similar vibes to Iron Lung with this game in terms of the feeling of exploring an unknown world. In Iron Lung, however, the player isn't just pressing a button that brings them to the next location. They are watching the radar to make sure they don't bump into anything as well as using the camera to get a look at their surroundings.
I feel like it would've been nice to maybe scavenge some materials from nearby locations. Perhaps we could've also taken some of the fallen androids with us to later get turned into more materials (not that that would've happened since we are supposed to die down there).
Overall, I think this was a pretty nice game. I wish you the best of luck in any future projects you work on.
Edit: Feel free to ignore the ending of the video. It really only talks about the same stuff as I did here in less detail.
