I’m glad you like it, it was a huge amount of work!
Thanks for your feedback. Designing levels of increasing difficulty was challenging, it’s good to hear that it is correct. I expect the player to do both inspecting the program and observing the robot behavior in order to understand the program. But I agree that the “action”/“target” is not very clear and could be improved. Such kind kind of new and unique game mechanics are hard to introduce to the player… in my to-do list for the next update :)
