I think it is still recoverable if we can come up with some new features to attract people back to the coin, especially with the low difficulty. I hate to say it but being a bit spammy probably wouldn't hurt.

By looking through the forums the main thing people seem to want from coins (other than big exchanges) are games and competitions. How about a banner / coin design competition for actual designs paid in NDL? Again, possibly a bounty for someone to setup a games site that accepts NDL?

The other thing might be straight advertising, I got the idea from this thread https://bitcointalk.org/index.php?topic=412525.0, thousands of people a day being hit with a Noodle-tastic banner might help! (I have no affiliation with the site)
