Most difficult levels in existence?

[Ida]

"Commit Suicide?" is one of my favorite CCLP3 levels, even though no one is going to get it on their first try (unless they've looked at a map).

The thing is, you can use logic to figure it out eventually. The long run of chips in the corridor after the force floors are a dead giveaway; actually, I think the level would have been better if there had only been two or three chips there. It would have made the solution a bit more difficult to discover.

Edit: (Spoiler alert, for those who haven't played this level)

The reason for the many chips in the corridor was to make a second puzzle. The first puzzle is to get all the chips (since the chips in the corridor are not visible until you're in it, the player thinks she must get all other chips). The second puzzle is to get as few chips as possible, since you know you have to take all the chips in the corridor.

Maybe this 2-puzzle-thing could have been done in a more elegant way, but I couldn't think of one at that time...
