The game would be 100x better if the combat was expanded upon, currently its quite one dimensional, where you can only attack or power attack + running away. Why not add sequenced swings, shoving zombies, blocking, kicking zombies - even just improving the feel of existing combat animations would make the game feel very modern.
Its really what the game needs since atleast 80% of the game is killing zombies, the killing zombies aspect needs to be fun as well.
Please take this into consideration. Thank you for reading.
