Great visuals and use of lighting! The movement and controls felt modern. The inventory system was very functional. The world was pretty immersive. I liked that the theme played a role in the mechanics, even if taken very literally. I really enjoyed this and intend to go back to it.
First playthrough, I got as far as getting the lab key, but fell through the floor running down the ramp from outside. There are other issues with meshes here and there. The gameplay did start feeling redundant, and some aspects hurt the immersion. But despite all that, I felt like I was playing an actual game.
Great work! I look forward to finishing this game and playing your next one :-)
