Nicely done!
I like the glow effect added to some of the objects and the fade out and in idea is awesome. The music fit perfectly and gave the game a very relaxing, but almost eerie vibe.
Level length also felt just right
It felt like the player "hit box" was a little larger than it should have been though, I kept bumping into pointy things even though I felt that I shouldn't have.
The player character also felt a little unresponsive at times - but I've noticed most of the games feel this way when played in a browser, so it could just be that.
Overall - awesome job, keep it up!
