Loving this! I was a big fan of OFDP/OFDP2, and it's great to see a game take the concept further.
My only quibble with the PC version as it stands so far is the button mapping. I prefer playing with the face buttons on the XBox controller, and while it appears the X and B buttons are supported, the B button also pauses the game, so it's not really usable. (I'm aware the PC build is still in development, so I understand that there's going to be a few things like this.)
