Two things I did not like about this game. First is the point-click, hidden object was annoying and mainly consisted of randomly clicking things. Second is the core game is not fair if you don't know the arrangement as they just give you the melody, and for many of the puzzles it's impossible to figure out which piece goes where based just on color and the melody as there are pieces which are the same shape with the same colors in the same places, and no red parts.
One of the best tower defense games I've ever played, but there is one major issue with the control scheme and that's the fact it's different from when you click on a building or a unit, but it does the same things, and it leads to some many wrong commands.
Note: This game does not actually have anything to do with music. Kongregate just forced me to add that as a tag and "Music & More" was the best way to describe this game. Please add an option to add webtoys!
