I got 64! And I would have kept going if 3 arcades didn't merge into 1 and prevent me from progressing. But alas, it happens. You actually minimized the bugs fairly well. Because of the progression and the way the game is paced (4 arcades per level) the bugs were hardly noticeable once I found the right distance to push the machines from. So, besides the clipping problems, I'd say this is a success. Well done :)
