Awe that was a lovely little point and click! Loved the Robo Dog haha! My only complaint would be that it felt a little directionless at first but that just makes it like any of the earlier Sierra games anyway. That was awesome though :)
Oh and not sure if you would want to do them or not but if you want to make any voice sound more robotic or machine like just open the file up (I used audacity for this), duplicate the voice then just slide it across! I found out this little trick while doing voices for my own project
