A very interesting concept, and the themes of loneliness and isolation really do come through. I thought the voice acting was pretty good for the robot holograms (holobots? Haha!) that I encountered, and the whole thing was very nice to look at.
The glitches made things a little bit difficult to navigate at times though, and the item usage system is a bit off (auto-using items on things can make the gameplay a bit wonky!).
But don't for a second think I didn't enjoy the experience! I really did get sucked into this sandy futuristic dystopia for a little while, and there's some lovely little ideas in here. Keep up the good work! =)
