Thankyou for reporting the bug and playing our game. I think I forgot to fix the hitbox of most the thing. I tried to make the tree not spawning on screen, but for some reason they still keep spawning. Also I guess I should make the zombie disappear after a while. Lastly I don't know why I tried to make the zombie only move when its see you so that why when you hug the tree the zombie stop moving. (I think this issue could've been fix If I do some play testing)
