I was playing my brother's Godzilla Premium the other day and the very first game, I got an airball that landed between Mecha's head and left arm...well, right arm if you're looking directly at him. Had to scoot the glass down a little to remove that one.
Are his arms adjustable at all? My brother is still too scared to pull the glass lol...so hopefully this doesn't happen to him when I'm not there.
