hint on how to beat greg get a demon with a horse class and a ice lance *thats all u need* and make sure you have all of the upgrades then spam loads of the demon and boost and heal it when the demon gets to greg he will be frozen and then u might need to wait about 2 hours
oh yea if u start a lvl and u wait without pressing the START ur sub weapon recharges lol? it would be nice if u removed this bug so it would be nicer (somehow)
Good suggestion... unfortunately, a little too hard to implement in this game. will take note of it for future games!
