The remarks about loose control, especially over the rockets... are absolutely untrue. The only control issue is with carrying/placing objects with the grapple arm. The ship control and rocket control is fine, there's absolutely nothing wrong with it. The "narrow corridors" mentioned that rockets need to be navigated through give you such a huge margin for error that it'd be tough to fail. Plus each rocket can hit a wall, what, like five times before it blows? That's the very last thing to complain about in this game. Says something about twitch reflexes as well, which is so off. It's a floaty, relaxing game 90% of the time. I can think of maybe two bosses that require quick reactions.
It also overestimates length. Took me about four hours to collect all but one object and finish the game.
Bastion is the best of the Summer lineup this year. There's no question about that. ITSP is alright, but it's tough to recommend at $15. There's always multiplayer, which is basically a score attack, but there's no guarantee that you'll personally find value there.
Don't go in expecting a great soundtrack either -- there's only one song in the game, and it plays exclusively during the opening and ending cutscenes.
