Oh no! You're not the first. My best guess is you ran into the same issue as some streamers that I watched -- TL;DR the codes in the manual are multi-character most of the time. The first page of "Arms" tells you the first key of the arm code. So for the robot left arm, the code is "al bp"
If that wasn't your issue please reply bc you might have seen a bug no one else has! I'd love to know about it in that case :)
Thanks for the play!! I'll play and rate yours soon :D
