Lightfoot from the get-go looks really nice. It has simple shapes, but that helps the lights stand out really nicely.
Having someone talk to you and give you information isn't a bad idea, but I would have liked it to be more concise - it felt like the instructions/objectives were rambling on unnecessarily. There were quite a few 'uhm...' bits in there that sounded insecure and out of place for an overseer giving instructions. If you manage to get through certain bits too quickly the voice logs start playing over the top of one another as well.
All in all the simplicity of the sky-city looks nice, as does the HUD overlay. Wallrunning/jumping to complete puzzles is fun as well. If the voice logs were to be improved I would not mind playing this several times more to see how fast I could complete it.
