unplayable, seriously? Guys, on normal difficulty I am right now 2/3 through the game, I have something like 15 extra lives stored up, and have only died twice (on the first/second level due to learning curve mostly). You can also exit anytime and pick up where you left off.

So if you are a casual gamer worried about the no saves thing, relax -- you get plenty of extra lives, health is abundant, and there is a hub where you go in between levels and you can exit the game and continue where you left off. This is not like old consoles where there was no saving at all, and if you wanted to beat the game you either had to do it in one sitting or leave the system paused and the TV off while you were sleeping etc.

There is also a level select where you can play any level you have beaten if you just want a quick game. Maybe on hard difficulty it'll be different but so far on normal it has just been a fun, easy shooter and I haven't even noticed the lack of a save-anywhere feature.
