Escape from Volantium

Your spaceship is trapped in a maze on an alien world. To escape, you must pass through a series of chambers of increasing complexity (up to some maximum difficulty that is selected at the start of the game). In each chamber, you must destroy the sentry to open a door and escape through it. But if you are too slow to flee the level, the sentry is replaced, the door is closed, and you must try again.

The major difficulty in the game is in controlling your ship, which has a great deal of inertia. Accidentally colliding with a wall will cause you to bounce in the opposite direction, losing control and incurring a time penalty. Occasionally, the sentry will teleport to another part of the room. It will also teleport if you run into it.

There is no way of dying in the game. Instead, you need to escape from a certain number of chambers to win the game, and your overall score is the total amount of time used.
