I found the eye candy very well balanced with the interactivity. Not too much to obscure what we needed to find, but enough to keep the atmosphere engaging. The structural choice of having the door centralised in space was an excellent design decision. The sound effects were tasteful and appropriately complimentary rather than narrative.
As for criticisms, I would like the companion to be more integrated in the puzzles and progression, and I'd like to see how some of the assets polished up with smooth shading instead. I think this game could enjoy a higher poly count and remain as smooth to play. Gorgeous art style, though, I like being here.
