Wow, this was actually unique, and I really liked it. The way you implemented how you can do loops in this game is awesome, but here are some issues that I had:
The game is a bit not user-friendly. Yeah, sure, you gave instructions on how to move the robots, but if you imagine someone with no previous knowledge of programming, they would not understand this game at all. It would have been perfect if you had taught the player how to use the commands by forcing them, not just showing them a text.
Sometimes, commands wouldn't work at all, even if they were in the right sequence, which made things more confusing.
A little bit of user interaction would have been perfect. the buttons and all UI in this game had no sound, at least during my playtime.
Overall, nice game and unique implementation of the concept "loop," but it can be better. So keep it up! :D
