Reading the road map I thought that I could flashback to a puzzle that I didn't beat the time on without having to play the whole of the level again.
Did I misunderstand it?
This would mean another play through on top of insane difficulty which is not how the road map reads to me.
Step 3 - Flashback for puzzle times and missing collectibles
Step 2 - First playthrough - Normal difficulty
To minimize the amount of time you will spend playing the game, it is recommended that you make sure Campbell survives the plank at the end of case 1. This will allow you to successfully use the “Flashback” method for the second ending achievement. To do this though, you also cannot use Flashback to replay any levels until you complete this playthrough. If you flashback during this run, the game will revert back to the default ending and you will need to play twice.Other than that, all you need to worry about in this playthrough of the game is getting the collectibles. Jeffy x360a wrote a five star collectible guide, and you should follow it by the letter. If you miss a certain collectible it is exceedingly difficult to pinpoint which one was missed, so follow the guide! It can be found here. While doing this playthrough you will have to save the man (see "Compassion") and will most likely snag a few achievements for beating best times in puzzles. If you don't get them all, no worries, I'll cover those in a second
This will snag you all the achievements in the game except for Path of Flesh. In the guide I have listed where the puzzles can be easily accessed and the method for restoring checkpoints and beating the puzzles.
How do you know which levels are for what puzzles?
Do you have to play through the whole level again, mean 3 play throughs is needed to get normal and insane puzzles done?
This has all become a bit confusing, some help would be appreciated.
