Very cool game: Cool story, nice levels and mix-up of two game types! I really like the way you provided the instructions at the beginning. Additionally I think the difficulty is chosen very good: Not too easy but also not difficult. I needed some attempts to satisfy the king :).
The only thing which was a bit annoying was the flickering of the robot and the screen when you touch a corner. Compared to the rest you deliver with this game, this is just a minor thing.
