I cannot open a 7zip file. I ended up converting it to a ZIP and jumping through many hoops to play this.
Aaaaand it doesn't work. I can click and drag, but nothing stays... Can't go back to menu so I exit completely just to try again.
Badly made.
Maybe something got wrong in the many hoops when you converted it. For how to open a 7zip file see the comment of Toma below.
I did try that first. No luck.
I'm sorry. Can I give you a free download code for another of my games instead? One you don't have to unzip? dm criacuervos at bluewin dot ch
You don't have to. Thank you, though. =)
