Solitayre has made a bonus level that will be added to the "normal" ending. It's an autoscroll airship-style level with a bonus star - a perfect alternative if you were only able to grab 4 of the 5 bonus stars and want to unlock the alternate final level and whatnot ;)

In addition to incorporating this new level, I plan on adjusting a couple things for polish sake based on the reviews. Should have it up some point this week.
