So, I hadn’t quite finished everything in this game. There are some extra Atari Bonus levels you can only unlock with a code. I used the code and now wish I hadn’t bothered, as some of the Atari levels are stupidly difficult. I thought I’d seen difficult levels already, looks like I was wrong.

I don’t think I’ll bother trying to finish off this set, which will leave the game in an annoying state where I’ve completed it, but haven’t really.
