Just played the demo - really impressive!
I think the art style and tone are excellent and really compelling reasons to spend more time exploring the world and story.
I thought the writing was good but could potentially use a little polish and enrichment, aiming to create the feeling like these are very specific people with rich personalities and histories. Citizen Sleeper was a game that I thought did this incredibly well, though it may be too text-heavy a comparison for your game.
I also think the game could benefit a lot from a bit more sound work, especially during cutscenes. The visuals are so cool and really deserve some sound design to enhance them. I'd also be curious to see a bit more gameplay or puzzles, though I know this is just a short demo.
Overall I'm very excited to see where things go with Riley, Metamo, and Slushie. Great work!
