I liked the overall setting, and the concept is interesting, too—I see a lot of potential there.
However, I ran into a few issues that really dampened my enthusiasm. For one thing, I didn't know how to rotate the parts; I spent the first five minutes flying uncontrollably through space with just one thruster until I finally got a second one...
Even after I had more parts, the ship still wouldn't fly where I wanted or react the way I expected—basically, I just held down the button and hoped for the best.
Also, I felt the timer—or the difficulty of the building phase—was somewhat unnecessary given the nature of the attempts; I died or wrecked my ship so many times but still managed to win.
Still, as I said, I see a lot of potential in it.
