I might be missing an option but while you're doing the memory optimization puzzles is there a way to start over? The first few puzzles took me a huge number of attempts and now I"m worried it might affect the game later.

As far as I can tell, the turns do not affect game. Sit back and enjoy the show.

The only way to start over would be to restart the game. At least I havn't found a way to exit the puzzles myself.
