This game has a lot of charm, and doesn't feel condescending as many programming-based games often do.
I had to do a lot of experimentation to determine the exact effects of the instructions, because the left/right blocks in particular are not immediately intuitive. Once I understood that turning is delayed by one turn while Going, and that turning does not happen when against a wall, things started making more sense.
The artstyle in particular is awesome. The par was pretty simple to beat in each level once I understood the instructions.
