BrainCandy: I have always liked the concept of the game but there was too much percision timing, which reminded me of Drangon's Lair. Does the game give you more choices later on, or is it more or less a pretty movie where you need to press buttons at the right time to keep it moving? This is what it seemed to me to be from the first couple of minutes. If there is more to it, I'd like to know. I might give it another try--and at the bargain price of $9.99.
It's really not like that much, but there are some sequences where you have to figure out the timing. For an example, you might need to reach a certain location on the screen to hit a button or set up a shield, and if you run a step too far you won't time to cross back and place shields with sufficient spacing to protect yourself until somebody opens a door. There are also plenty of traps or lethal events you can only avoid with foreknowledge. If enduring this sort of thing every now and then makes you angry enough to spoil the experience, avoid the game.
On the other hand, most of what you do in the game won't involve that. You will spend a good amount of time figuring out how the world works, tracing connections between rooms, sometimes retracing your steps, otherwise analyzing your surroundings, and having some pretty awesome gunfights. What makes the gunfights interesting is that your weapon has limited charge in it and you'll need to decide how to divvy it up between conventional blasts, the shields it can lay down, and the super blast which can penetrate shields & doors. Almost every situation does have one correct approach, but the feel of it is a bit closer to Metroid 3 or the original Prince of Persia than it is to Dragon's Lair.

I don't remember the game well enough to say for certain if the way he approaches the situation is a puzzle solution or just good fighting, but after watching twice I've already forgotten the details so it's probably safe to look at.
