Meh
a few pointers..
1. Power-ups! where are the powerups?? maybe a bottle of moonshine to make you invincible for 15 seconds...a bottle of hot sauce to make him shoot fireballs from his crowbar
2. Weapons. Unlockable weapons are nice but you gotta have something more powerful in the field to really down your enemies..upgrades are nice too like a titanium crowbar or dual wield hatchets to lop off limbs.
3. Clustering. Alot of these enemies cluster around you..there is no escape from this..you need to add the E key for escape button..roll out..quick spin attack something to break free.
4. Add some cameos like Bruce Campbell for example..he doesn't have to fight but a humorous line or two would be nice
