Solid, but it didn't leave a strong impression. Would I have gotten more out of this if I'd played Guardian of Light? Or, hell, more original continuity Tombs Raider? Maybe, but even in a vacuum, it's a decent enough co-op experience. I don't think I ever really got much out of the Reward system (maybe if I was playing this more than just casually), or much of anything the game had to offer besides its physics puzzles and boss fights - but I did like both of those. If I'd been playing by myself, I probably would've found the game overly forgiving (definitely remember cheesing some of the crumbly bridge sequences), but I appreciate it in the context of a co-op, more puzzle-oriented game.
