well, i only got 9 flowers and i just need the achievement "fever" is it possible i start in chapter 10 or am i forced to start the game again from the beginning to get this achievement?

It should also be noted that you get this achievement when you look at the flowers in your apartment.I thought the achievement was glitched

Thank you

Nice screenshots guide !
Here are a few details about the flowers locations :
Tuesday 1,2,3 - Chapter 10 : Meadow, before following Halperin
Wednesday 1 - Chapter 16 : Observatory, on the left of entrance
Friday 1 - Chapter 26 : Before jumping down in the meadow, under your feet
Friday 2,3 - Chapter 26 : Meadow, before crossing the fence using the dead tree
Friday 4 - Chapter 26 : Meadow, after falling from the dead tree and before going into the pipe tunnel
Friday 5,6 - Chapter 26 : Meadow, after stepping out of the pipe tunnel and before taking Halperin's locket
Hope this helps :-)

Thank you!

Thank you! It helped me with the flower-related achievement.
A comment for Friday would have been nice stating the 6 flowers can be found in 3 separate places.

Thanks for your massive help!
