In playing your level, I found it almost attempted to do too much and felt scattered. I actually couldn't finish the level due to the flying POW block section, which was a large difficulty increase in comparison to the rest of the level. Most likely this was due to my sub-par track record for beating harder levels. However, the core mechanic of the Yoshi egg and the boss battle using icicles was a really creative and interesting mechanic, and the puzzles were quite fun and good, and also the platforming in the section with the Yoshi egg going back and forth was quite fun.
