Woooow this was a really nice game and a very interesting experience!! I really loved everything about it, the ambience, the "friendly" robot, the graphics, the audio and sfx. Overall just a really nice game! One thing that i would suggest is to reduce the volume fluctuations of the robot's voice with the distance because sometimes as you move away it becomes a little bit hard to understand him through the other sounds.
I got the almost bad ending hehe and really liked it. The game is surprisingly polished and its amazing that it has been done in 7 days, trully hope you keep working on the project!
