Fun
Its a good way to get some recognition for those amazing artists out there. great music! For the game aspect, i thought it was fun, the unlock feature makes you want to press forward in the game but the simplicity and basic track design doesnt.
Only 3 tower upgades (of which can be purchased very quickly), and you win by simply placing towers of the color in the analyzer ANYWHERE on the track (as long as you cover all 3 lanes. i was only placing 2/4 towers and not losing a life.... and theres no "best" tower to counter certain enemies, because theres only 4 types that differ based on speed alone. basically im saying theres no real strategy to the game at all which is my biggest gripe.
Dont get me wrong, its not a bad game and definitely worth playing the first song or two but I couldnt see myself spending an hour or two playing the same thing over and over but to different songs.
