Definitely an interesting game.
Remember that not all devices have (web)cams (my PC doesn't), so don't make it too dependend on that (I assume the frames that I shouldn't look at would have contained pictures from the webcam).
For my taste the robot was spelling out the solutions to the puzzles too fast, even with simple puzzles there will be one or two that a given player may need more time on.
But again, an interesting game that I'm looking forward to seeing more of.
