Really easy, it needs levels :D
What do you get when you combine the superb Away3D, the Flod soundtracker replay library, and a heavy dose of late 80s Atari/Amiga demo scene influences? You get this oddity of a game, that's what :)
The initial code was put together over the space of one lunch break. The demo effects are all from pre-existing libraries I had written. The graphics I either created or had already (the background was purchased from Renderosity Marketplace for example). The music took a while to select though, I went through a number of tracker mods before settling on the final tune. I then tweaked, tested, Mochi wrapped and kicked out into the night. All in, 12 hours work. And I'm perfectly happy with that. It's not exactly an earth shattering game, but it's a nice 10min mental challenge if you're up for it.

Wonderful
Once I figured out the tricks it all became easy though. Don't know how to improve on that :(. Still, it was good.
Pretty fun.
It's simple, entertaining, looks nice, controls well. The only complaint I can level against it is that the music is way too loud. I appreciate the mute button, but it could use some balancing. The keyboard shortcuts are nice. I would consider adding some difficulty levels that expand the field between 3x3 to 6x6 or so. Maybe also add a leader board based on quickest times. Those would cool additions.
It okay
I never really liked these kinds of puzzle games. Their only trial and error and offer nothing else. But if you like that stuff than its okay.
