It's an interesting level, I've never played a KS level focused exclusively on boss battles. Graphics are simple but nice looking. PP may have a point there with the springs, they are kinda hard to see when they blend with the background.
As for the gameplay... the level is short and fun, but also pretty frustrating at some spots. For the most part, you just have to figure out the correct pattern and practice a little (the autosave allows you do so without having to restart the battle from the beginning). But the later stages of the last boss have some VERY cheap moments:
The most irritating one was the part where you have to dodge enemy fireballs while climbing up a platform. The enemy on the left isn't always in the same position, so the fireballs can come in an angle that is pretty much impossible to dodge. You have basically to try again and again until you can make that jump... and then you must be very careful with the enemy on the ceiling. It's not a good idea to make challenges that rely too much on luck and randomness.
Also, this level feels like it was rushed to completion. The fact the title is wrong (as SecretGlitch pointed out), the lack of a proper title screen and the duration of the adventure makes me think so. You sport some original ideas, but it's a shame you didn't take the time to develop and polish your level more. It feels empty when you're not battling a boss... you could have extended the areas and included some puzzles or minor challenges between bosses (like exploring the area to find a key which would let you access the boss).
Overall, it's an interesting level, but there are a few issues that drag it down. For the record, I liked your previous level (Juni's Dream) more than this one... It felt more complete and the story was more developed. However, this is an interesting experiment... you could recycle some of the ideas you used on this on your future, bigger levels
And lastly... I know this might make me sound like a dick, but... remember to not only try to improve your grammar, but your spelling as well. Man, the title of the level is just barely legible
