Hello Polana,
Congratulations on this great level. I finished it on easy last night. I found it refreshing, fun again and I love the color combinations (I love all colors). It was challenging without being out of reach. I found the rock band which made me laugh ;-)
I also loved the little fur balls, it made me think of Fury Of The Furries on the Amiga. I really liked the vertical world too
if it interests you, I found a little sound bug: it's in the 1st world, a level in the shape of a sink where you have to jump above a hairy beast which goes very fast and above a kind of spinning top that oscillates to the right and left. The sound of the save in this place is that of the sound when you take a power or a key
I'm going to try hard mode now. Well done ;-)
