Rollers of the Realm is, as you probably already know, a pinball game meets an RPG. Your two main flippers have HP bars, and will break if they are attacked enough, becoming shorter as time goes on. Each character/ball has their own attributes; the knight is a larger ball that is slower but does good damage, the thief is smaller and faster and can summon her dog to help her out (multiball), that sort of thing. The story is pretty standard RPG fare, but the gameplay is what makes it really fun. It can get surprisingly challenging, especially when you want to figure out how to both defeat your enemies and get the treasures hidden around a specific level. Personally, I love it, and especially since it's on sale, I highly recommend it.
