Nice little game!
Probably the saddest part is the length, because I really enjoyed this unique take on the theme. Of all of the "program an ai to move" games I found this one the most enjoyable. Since it felt like you had to just think more logically, instead of the many other games where you just have to predict the movement for the entire level.
Small additions like having all the Discs be viewable at the start of a level, so players don't have to spend their beginning time moving to see what everything does would be nice. I also think a designated "start" button would help, since sometimes the robot would move before I had finished creating all my instructions.
There is plenty of room here for growth, with obviously more levels and more command types, would be cool to see how complicated something like this could be.
Nice job!
