a few things to improve on
1.)I dont know if this is a mistake, but in hellfire form, you only showed true demon colors whilst attacking, and was deprived of a should-be major speed boost.
2.)Jumping was sort of fucked, you stopped midway and could not change directions or move while jumping, the boss, whom u had to shoot at until his combo was over, was harder than he should be because i couldnt aim my jumps to be directly over him.
3.)The demon bar went down a tad too fast in my opinion, just a heads up, others may have same problem.
4.)upping the skill bar was too easy, because of the ability to do an endless combo.
5.)Enemies would go off screen. making re-entry time and place unpredictable, thus destrying the skill meter so far.
6.)the demon doors (red) had way too many enemies, which had way too much health, if you make a DMC trib. think of the style of the game, extreme amount of enemies, low health.
7.) other than this amazing game, almost on par with the first one, expecting full version! I loved the new monster designs, but they could be better drawn, the pixels were visible making the monsters look bad around the curves.
