Okay, I need to know the lore of the DoCS--would absolutely play a full length version of this. The portal inspiration is evident. I also loved the train sound effects between levels and all the clicks of the flashlight--I wanted to play with every object in the room. I'm imagining more 3D puzzles where I can make stairs out of objects or something or perhaps use objects for non-original purposes (like maybe, I shrink a closed umbrella to press a reset button on a device like it's a toothpick). Very nicely done!
