I have to say this idea is very original. I liked the puzzle aspect of the mechanics, it's all really clever and well executed. But I have to say that I think that the gameplay is too slow and cumbersome, you spend more time executing the commands than solving the puzzles themselves. But yeah, seeing that lots of people liked it, maybe it's just me?
Hahaha, anyway, I have to commend your implementation of the concept. It's all very well thought. Congratulations!
