I don't think I looked at the othe walkthroughs about this.

On reflection and as far as I remember - I seem to remember that I found it difficult to get the mouse to the correct positin left/right and then shoot.
It may have been that I hadn't 'learnt' that you only need to clear a path through the middle and not waste time clearing the 2 sides? And hence I would have had no trouble using the mouse.

Unfortunately due to the fact that there are only the ridiculously small number of save slots (6 in all) I can't now return to check this one way or another.
Cheers.

Walkthroughs were not out when I played and I did not find them necessary. I thought the in game clues were brilliant and easy to follow. I had no difficulties in playing at all. Maybe the walkthrough make the solves more difficult then they really are.

I found a lot of the puzzles very difficult - especially the arcade, platform and timed ones.

My 'echanical' aptitudes and eyesight are not what they used to be so I had troubles.

As far as i remember there was only one sliderpuzzle in M: and it was easy and had a clever twist to it. Nothing to be afraid of, take that from a sliderhater.

My take is the same as Ana's - brilliant in-game clues with clever and, yes, difficult puzzles. I think easy puzzles would have been a detraction from a wonderful game.

However, I did use my keyboard instead of the gamepad for one of the arcade games and it did make it much easier.
