How do I pass through a door with the Mech, in NOVA 2?

Question

I am on one of the first levels of NOVA 2, where I entered in a factory, and jumped in a Mech. I am then taken in a room where I have to destroy six tanks, and four Mechs; from there, I have to go in another room, but the Mech doesn't pass through the door. I tried finding another path to reach the point I should reach, but the only way seems to be passing through that door. I cannot jump off the Mech, as the "E" key doesn't seem to have any effect (and I didn't set another key instead of "E").

There are five other doors, but I can use just three of them. I was able to pass through two doors, but they take me to a room without other doors; the remaining doors are the one to which I am directed, and the one that faces on the ocean, which is blocked.

How can I pass through that door? I also tried side-walking but that didn't help.

The main objective reported is the following one:

Get into the courtyard and clean out any resistance.

The log reports the following sentence:

There is heavy resistance amassed outside. I would hold on to that Mech.

Answer 1

As silly as it could seem, the solution is to keep wiggling until the Mech passes through the door; this means I kept pressing the arrow keys until I would be inside. Maybe the position of the Mech helped too, as it was facing to the side; maybe it is just a coincidence, and wiggling made the trick.

Playing the game on a iPod/iPhone, I guess that you should enable a different way to control the game, such the one using the accelerometer.
