There are some browser games that allow you to put together various things, such as a party of adventurers, or maybe a bridge, but this is the first we've played that lets you put together a spaceship module by module.
Farb's new game, which is apparently untitled at the moment (or titled, but we just don't know it!), is a fantastic romp through a hectic region of space where ships are rapidly building themselves up after a catastrophic explosion. Time to survive.
You start off as a single, no-parts-attached ship with a small booster and laser on the front. Soon enough, small ships with other bits and pieces begin to attack in a bid to make themselves bigger. By rapidly turning it around on them, you can grow bigger and bigger, increasing the difficulty of the game, until you fight the end boss. The whole "build your ship out of individual parts" is a great concept, and the smooth vector graphics make it a delight to watch in action.
Edit: It appears that there was some miscommunication, and the game was intended to be in CLOSED beta. Whups! Keep an eye on the site for more updates.
