I've found 8/10 but I cannot for the life of me find the remaining two. I don't know if the order of the cards is important in figuring out where they are in the days? Does anyone know or can help me?

I wonder where is the first card in the collected cards. I found nine but couldn't find the first one, help!

I completed the game and found one small bug with the current version: Bug (game may tell wrong objective on Day 2): If you finish all tasks at the motel on Day 2 until the game tells you to clean the kitchen. If you instead of cleaning the kitchen go to the back and open the dumpster where you find the cat. Then pick up the cat and give it to the lady, the game after that says incorrectly that the objective is "Take the Next Order". But the objective is still actually to clean the kitchen. ...

what is the email to contact the devs and how many chapters/hours is the game?

Have you considered a release on GOG? I love the old-fashioned atmosphere.
