Very interesting and original gaming mechanic, from my standpoint, at least. I was not very impressed at first, but as I started playing the gaming idea in all its brilliant simplicity came to me.
My three major criterions in any game analysis are the extent to which game utilizes its gameplay mechanics, how this mechanics interact with the story and artistic style to produce an integral aesthetic experience of a game, and how fun and interesting this experience is to me.
The actual gameplay mechanics here I think are great. Their main advantage lies in their flexibility and modularity, which allow for many new variations with initial components. Each puzzle allows endless replayability, as it combines elements of both shooter and puzzle and requires logical thinking, spatial coordination and great deal of reaction. You can perfect your score endlessly, and leader boards are actively encouraging you to do so.
Visual style, music and setting I found serviceable, but not interesting enough to drag me into the game's space even more. It felt pretty abstract, functional, which is enough for extensive level creating possibilities, but not enough for more intensive gameplay experience.
I think as it is this game is a decent introduction of some great gameplay mechanics, which open opportunities for new ways of producing meaningful gameplay experience. It is less a game and more a construction kit for inventive spatial puzzles. I think that its core idea could be developed further into a full game - maybe with more thought-out setting, visual style and story.
