It started as a 48-hour Ludum Dare competition entry, made over a weekend - the contest version did pretty well in the judging, #81 out of 1072 entries. Over the next 3 weeks or so I pimped out the graphics and interface, and released it on Xbox Live Indie Games.
It's got some pretty big flaws, in retrospect - the early levels rely too much on dexterity, rather than puzzle solving, which I think turned people off (controls on the analog stick are a little touchy - D-pad/arrow keys work better). As you pass level 15 or so, the puzzles get a bit more interesting, but unfortunately most people bowed out before then (I un-wisely put the demo cutoff at 15 levels). More playtesting would have helped. There's a funny, brutal review from Indie Game Girl on it.
In spite of all that, I'm glad to have finished it, and for the most part I like how it came out.
