Hi, just started the game this night, it's really cute and I've been having fun with the decently complex puzzles, but there seems to be a controller issue that's keeping me from getting past the Minibot Puzzle. Upon entering this puzzle, the robots refuse to switch, which gets me stuck right after finishing the circuit.

I can still get red bot to pick up blue bot (blue bot walks up to it and performs an action, it changes to red with blue on top, I can then move blue to the shelf, do an action again to turn back to blue), then enter the gap. I've deactivated all three buttons successfully and then exited, but am blocked off by boulders. Doing an action (Z) just makes blue sweatdrop, and switch (S) does nothing.

Any advice?
