Really innovative idea! I like this game a lot, but I think it lacks tension - it needs something that makes decisions difficult once the player figures out the game. I think the most common way to add tension is a timer (maybe you automatically rule that its a draw if your timer runs out?) but you could also add some longer-term requirements, like maybe having to pay money every 10 rounds for rent or whatever so there's some incentive to take the bribes in addition to the disincentivizing corruption bar.
Again though, great idea! Keeping this bookmarked so I remember to give it a good score tomorrow ^^
