Nice work on the level and content progression! I would ask myself, "Are there just patrolling guards?", then the next level would have cameras, or "Can I just pick up everything?", then I would find a really heavy piece and need to drop it. It was always a step ahead.
The time pressure was very welcome because I had so much fun taking risks while zooming through the level and dealing with guards or hugging walls in front of cameras. If I could be careful all the time, I would end up boring myself.
Great job!
