I appreciate your feedback. Yeah, the combat is definitely not perfect, nor is movement. I decided to put a collider around the sword, and whenever it touches the enemy, it causes damage, but the range of motion of the sword could be a lot wider. I quickly made an animation for the sword, to stack on top of my character Attack animation, and if I work on this more I'll made it a nice wide, sweeping attack.
Lvl three was intended to have a key that you need to pickup in order to leave, but for the sake of time I just made you have to kill all the zombies.
I'd love to hear more about your thoughts on what kind of tank controls would be beneficial, because I might expand on this project later. Do you mean like blocking or dodging? Blocking could probably help a lot.
