A huge exploit was fixed where you could break the layer transition with the grappling hook so as long as you had a layer transition anywhere like some stairs, you could effectively go up or down while staying on the same layer making you able to walk through walls. Thanks to Beardlass for finding this bug! =) Another huge thing in this patch is that the knockback that enemies suffer when you are hitting them is sooo much smoother now. It's an actual animation instead of an instant knockback effect.
