Very cool idea for a game. Great use of the theme. The waltzy music was great, and it fit the Russian-theme nicely; I love the Papers Please nostalgia.
To be perfectly honest, I found the game a bit too easy. I made it through on my first attempt. Tried again with different skills and items and made it through again, just fine. Too much challenge can be a problem in a game jam game, so I understand the issue of balance (I personally suck at it), but things felt a little too easy IMO.
Still, very cool submission.
