XD tried to move with wasd, definated helped abit , but somehow it get bit distracting and caused a few unwanted death at times(bump into monster etc.
Btw , as I was replaying with moving the charater, the slow down time can be shown as you cutting of the monsters one by one(so the more you kill the longer the animation will be thus more time to plan on next strike.) You will still be able to move your mouse or even click on the very next location while the animation is playing!
