I like the idea of the game to have only one live, but the game developed to be more a guitar hero game than an actual interesting experience of having one live only.
I got to 1754 points... and was board.
This game isn't really a rhythm game and it allows me just just randomly hit buttons and still win.
The one-life thing is pretty pointless in a game that gives you no reason to survive, or care about surviving. It's completely arbitrary without something to care for, and with a gameplay style that's generic. Additionally, if you spam all the buttons, you aren't punished.
