Wow. Usually when there's only a few reviews, there is still much to be said, but most of it's pretty much been covered. I agree, this game was short, but the replayability is definitely there. The achievements are well-balanced, some are very easy, some are very difficult, but none are impossible. Music was catchy (maybe a little too much so :P). Ricochet physics is a nice innovative, yet simple mechanic (although it is being used more and more, it's not quite mainstream yet imo). The randomness fits with the Ludum Dare theme, and has a nice lulz-factor. 4.5 as a LD submission, probably in my personal top 5 (though I haven't formally created one yet lol), and 3.5 stars if you were to consider this as a finished project. Very well done :)
