Battle, by 
Dingle Dell? Sounds kind of Christmas-like, right? Even though the music somewhat carries that theme, this level actually fits perfectly with the current time of year. No, seriously: Violet, what an amazing piece of art you've created!
Yes, everyone: our amazing level builder once again delivers something truly magnificent for all of us JJ2 fans to enjoy. The layout of this level is quite simple, which works really well for me, since I tend to get lost easily. It's basically a matter of going down, after which you're launched back up and start over again. Along the way, there are tons of goodies for you to collect. It might sound a bit boring the way I describe it, and I think more experienced players might find this level slightly less engaging.
That said, there's still plenty to admire in the colorful eye candy this level offers. The vibrant background and the falling blossoms give the level a very cheerful feel. Also, I'm really impressed by your introduction of those colored springs, which launch you all the way back up the stage. It was incredibly satisfying to use them!
All in all, I'm giving this level a well-deserved rating of 9. Amazing work, Violet!
