Hmm... I tried running the game and pressing 'G' at various points in the beginning to no effect. I checked the code, too, and there's nothing about the 'G' key doing anything. If anyone else has this problem, tell me and I'll look into it more deeply, but I think that it is just your computer acting up.
As for Syobon Action... yeah, I was playing a lot of it during this portion's development ^^;
