Hi again Tania, thanks for your response, I really appreciate it.
I clicked on those locks on the bottom left side but nothing happens.
May be it is the version of the game? I'm using the Final version downloaded from this thread. In this version the locks are golden while in your screenshot the locks are silver.

Also in my version when you advance in the game these locks are replaced with items that you can purchase but there is no option to purchase coins.
May be I need to do something different?
Can you share some insight?
Thank you very much
