Developer Camoflaj has dropped the first two episodes of Republique so far, and you'll be able to nab the first one starting today for free. From June 5th to the 12th, you can download the first episode as part of Apple's "Free App of the Week" promotion -- so go do it!
If you're so inclined you can also pick the next episode up for $4.99, or just pony up for the Season Pass for $14.99. Since the second episode is a lot stronger than the first, this is a good time to give the game a try and see how it plays. Keep in mind though that the last episode isn't scheduled until later this year.
