I loved your entry Magecore!
The first perfect score I gave away <3
Even as that, I have some feedback for you...
The first I would change the rhythm bar color, because at first for some time I thought only yellow was available, to solve this I would use a purple with the same level of saturation of that yellow... Would fit very well your game;
I would leave the rhythm bar more centered somewhere in the screen, because for a long time I keep staring just at the bar, and forgot to see how beautiful the game was;
A balancing of the turrets would be good, maybe making some kind of rock, papers & scissors like mechanics, so it would actually force the player to use other towers without being hard to balance and understand;
And last: not sure if had, but a goal in the end and a small finish screen or something would be nice!
Congratulations! <3
