This game is really, really good. It took me back to games I'd play on my dad's iPhone as a kid, but so much more polished (really impressive the fact you made this game feel so good to play in such a short amount of time!) I think out of all entries so far, this one gave me the deepest sense of immersion / flow state. Easy to learn, hard to master. Rewards discipline and quick thinking.
By the way, the Drum & Bass soundtrack, too, was hypnotizing. It's like I looked at the clock and WOW an hour had passed!
