Mineshaft is a fairly easy level that features vertical gravity lines and far too much silly writing!
Feedback would be lovely. Design stuff after the break. Play the level first!
With this level, I wanted to do something that the original VVVVVV levels didn't: Provide a strong sense of place. The Laboratory was great fun (probably my favourite level), but it didn't look or feel a lot like a laboratory -- intentionally, I presume. I wanted to try something diffirent! Armed with the wise words of anna anthropy (http://www.auntiepixelante.com/?p=475), I set about building rooms that made it feel like you were descending into an abandoned mine.
In the end, I don't think I quite made it. The problem is that providing a strong sense of place requires a lot of complicated visuals, and when I tried to combine complicated visuals and complicated challenges, the result was not pretty. Because of this, all of the pretty screens (the Mineshafts, Surface, Down and Around) have very simple challenges. All of the complicated screens (Gap Selection, Love Storage, Breakout) have visuals that are as simple as possible, and bear almost no resemblance to any logical, man-made structure.
Despite this, I'm pretty happy with how the level turned out. It was fun!
EDIT: Also, Paced Energy is awesome!
