Nice
Nice game, managed to finish it with 219 commands. I'm not a programmer, so using redundant functions in level 11 was completely strange to me. I guess I'm used to no redundancy in puzzle games, and this was a good new experience. I'm not even sure redundant functions were needed in level 11, but I couldn't beat it in any other way.
I've been wanting to learn a programming language for ages... this little game got me thinking about it again.
Though it's not a new idea (there's one other game on Newgrounds like this one, called Bill the robot) it's very well done, nice animation and feel to it. 10/10.
