The concept behind the game is really nice, but something's missing to me, maybe some balance on how the bars work? The game's style could be really used for a more puzzle-like approach.
Having to use the mouse for clicking feels kinda strange too. Maybe concentrate everything on the keyboard and add something more action-like, something more...uh...dynamic/fast/something? :P
But good job! :D Also +2 because of Love2D! :D
