Thank you! No, there’s no way to avoid taking damage during a dash. The idea is to throw your sword behind the enemy and, once the sword is out, move your character to align a "direct line" to your sword so you can release and dash to it without taking damage. However, for enemies with only 1 HP left, you can click and release instantly, as they’ll be destroyed before you reach them.
I’m not sure if that’s very clear XD The gameplay isn’t polished yet, and there are still a lot of timing adjustments missing.
