Glad I stuck through it after the first few days, I was struggling to find the robot and the bike but decided to kept going deeper. I wasn't expecting what happened next lol.
The visual style wasn't selling me at first, but it worked a lot better underground than it did above. I think a little bit of sound design would have gone a long way towards a more compelling experience. Some cave sounds, a drone sound that changes when you move direction, ect.
I think the pacing was pretty good, it didn't drag on too long or finish too early, I felt like i got exactly what I was supposed to out of it.
