Looks like an interesting game, but unfortunately I don't have a Mac.

You can tell right away that you put a lot of work into the game. 
You even attached a very detailed gdd. 
the game itself also makes a very good impression. 
It's also fantastic that you created a paper prototype.
 I played the Mac version.
 I only noticed 2 things that you could possibly change. 
If I'm standing on the far left wall and then play a card that makes me go to the left,
 I'll stay there. 
In the Mac version it is not possible to exit the game with ESC. 
I had to close it hard.
very good game and a nice submission :)
