BUG REPORT: If you spin the dials of the blue safe, the key (for the drawer below the safe) becomes unusable.
Apart from that bug, the passwords and puzzles were pretty simple. The math puzzles were a nice change of pace. It was mainly a matter of running back and forth, plugging numbers and words wherever they fit... or it would have been, if not for that bug. I noticed that most of the locks (except the kitchen cabinet) are immune to brute-force password testing. Well, you're allowed to choose that, but making the game secretly unwinnable just for experimenting too early is outright unfair.
Also, get a grammar editor because that game description made no sense. I had no idea what the robot was supposed to do. (As it turns out, it was just a lame MacGuffin.)
As a puzzle, it's simple but passable, but the lack of polish hurts badly.
