I really enjoyed the sound track, so long as you take it in small doses. The puzzles are clever and the setting is very interesting.
However, toward the end of my playtime, I felt like I was just guessing at where objects would land and what colors they'd turn into. No track or color scheme was made very clear so I eventually lost interest as I didn't feel like investigating much outside the core game itself.
It'd be easy to get much more out of the game if you're willing to reach outside help and hints.
