It's okay. I found the controls clunky, particularly when it came to opening objects (especially doors). Puzzles were either easy or very obtuse. Didn't feel like there were enough subtler hints placed within each space to avoid using the optional hint system from the settings. The settings hint system also seems to be linear? It was giving me hints for a part of a level I hadn't even gotten to yet rather than for the area I was working in and the objects I had in my inventory. Also found the time/x-ray vision mechanic to not be well implemented. Often could not tell something of that sort was needed unless I was at the exact zoom level where it would be used so there would be no clue that you needed it. This is particularly odd for the time watching because it's supposed to have a particle effect that's visible to tell you that it can be used in that spot in the first place. Overall I played it for longer than I should have and didn't finish it because it was too clunky going back and forth to try different solutions.
