This was a fun one!
First of all - I love the interpretation of the theme. It's very original to use a legal term such as 'void contract' for this!
It's clearly inspired by Paper's Please, but it has it's own fun personality. The writing is witty, and the sprinkles of humor in the game are hilarious.
The game has a great learning curve to it - my first run was a complete blunder - I failed EVERY SINGLE CONTRACT, while trying to figure out how to play the game. And my second one I perfected the game - it's AWESOME that the game actually requires paying attention and learning to be able to complete it.
The UI is fun to use and generally responsive, except for some minor nitpicks, like the book being hard to move around. Also, there is the page in the book with the label 'void' in it - it threw me off. I thought all the demons that were in that page MUST be voided, but it ended up being just an aesthetic choice.
The artstyle - character portraits are great, and I love the little animations in the UI, like the mouse cursor for example.
I love the music - it's really fun, the main menu theme is very groovy.
The game unfortunately froze for me on Friday - there was a black screen, music was playing, and nothing happened afterwards.
