You've just murdered Devil May Cry...
Wow. You've taken a brilliant game and crushed its good name. It really dissapoints me when i see the icon of a game and i think "Ooh, that looks good" but after around 3 minutes i think "Why did i waste my time with this?". For starters, The controls were messed up, you could only do 1 combo and the automatic weapons weren't even automatic. Secondly, A plot would be nice. What's so fun about getting thrown into a small area and constantly killing the same thing over and over again with weapons that barely do any damage?
Thirdly, It not very original. The fact that you used a character that is the mirror image of Dante except with black hair kinda put me off. Also, the shopping feature is the same and even the items you buy and use were the same as Devil May Cry.
Lastly, The game has brilliant graphic work but all that is let down by the lack of entertainment. To me, it seems like this is a rushed attempt at making a good looking game that, put simply, isnt good at all.
I cant blame you for trying though, but you need to make your own ideas. Change the character, add a storyline and dialogue, mix up the monsters you fight and not use ideas from Devil May Cry! Use these tips and you culd have a good game made.
