Really amazing game! I can't believe this hasn't gotten more attention. Simple, easy to understand mechanics implemented well. And the music is just spectacular! I also love the individual leaderboards for each level. A lot of games like this just count your time for beating the entire game, but I like this better. I like that, if I wanted, I could get really good at one level and beat the top score on it.
My only slight complaint is the UI. Don't get me wrong, there are no bugs, but the default unity UI elements bugs me. Although that's probably just me.
Also, maybe you could check out/rate my game? :)
