Tried playing the game, but it crashed.
I then restarted, but the mechanics of the game really didn't work for me; the slicing with the mouse required a lot of travel and felt floaty; didn't know if the slicing was working or not (top plank was cut, the bottom one didn't respond after a few tries), so I gave up before getting through the path I'm afraid. Before the level started, the 'goal' screen felt slow; I wanted it to continue, so you might want to change the pacing there as well.
