I assure you, I enjoyed every minute of it! I like a good "numbers go up" game, and boy did the numbers go up! XD
Another couple suggestions, though, would be to make the infrastructure upgrades' expense and the cost of spying to scale up faster, because they're both super powerful features. And also for the bribe feature to be less consistent.
Again, really fun as is, and it's a hard balance to make the beginning not punishingly hard, while keeping the game consistent, engaging, challenging, and fun into an end game.
