Thank you for your feedback! Yeah, aiming and physics certainly need more work. I have also thought about the case where the head lands too close to the enemy and came up with the idea of giving the character's head a special ability of rolling back that can be activated by player after N amount of time. There also can be some cool mechanics with this feature (like boomerang attacks). Unfortunately, it was just a few hours before the deadline, so I couldn't implement it.
