I iked the game. Still things to tweak though. Like others mentioned movement and physics need some work and I was lacking some indicator that the knives do damage. Because the enemies needed quite a few hits I figured they didn't hurt them during the first run. Made me try four weaponless runs before I tried again with more hits.
I also didn't like the mouse to throw the knives. I can't aim with them so using another key on the keyboard would have felt more natural for me
