You really screwed this up lol. You could have taken the gameplay from Gunblood and expanded on it. Instead you just took the gameplay from Gunblood and slowed the combat way too much down.
Why isn't there a skip enemies turn button? I hate watching 15 billion zombies doing moves. Takes forever and if I cared I could just look around myself. I don't like waiting 10 billion minutes for their turn to be over.
These protection area missions are really bad, in the next game you should change how they work. Those missions are just really, really bad and annoying.
