Well put-together. I don't know if this was just me being bad, but if I may offer advice, try to make it so the time between the rows adding on starts slow, but then gets faster as the game goes on. Otherwise, great game, keep up the good work!
Repetetive music that restarts every minute or ..so... ...noticably... No initial help screen to explain the game, making the user rely on author comments to play. clutter media appears to be the right word as the most entertaining part is listening to a failure in music combinations. clicks overwhelm music with bursts of chimes. Guitar chords continue a few seconds out of tune.
Solid play for the matching puzzle play genre. matching characters which appear as though from .The Amazing World of Gumball.. a cactus.. no upgrades.. a single background and no sense of traction and onward movement progression. Find the point of the cactus and you could have a good game here.
