Yeah - this game is pretty cool - I've played through all of the levels, now I'm just trying to finish up the levels with Platinum medals for the overall level and the individual challenges, as well as also collecting all of the artifacts.
I'm not sure I want to re-do everything to the point of getting all of the achievements, but the game is pretty fun so I may stick with it long enough to do that.
I love that they worked Cad Bane into the game.
