Somehow it doesn't work in Firefox...it never quite seems to load, just stays at a gray screen. I had to play it in Chrome. Strange...
This was pretty great, though! The atmosphere is wonderful. I love the graphics and the way things explode into little shreds. I love the blocky shapes of the levels that represent stuff in the story...The story itself has a great tragic Japanese samurai ghost story feel. The gameplay is great too, it gets pretty chaotic with all those knives flying around! And I like how the knife powerups help get those last few blocks when you get near the end of the level.
Great job!
