This game is of a quality as high as its difficulty. I admit that I did not pay attention to its history. I completed it next to a friend, and what has cost us.
I love their levels, each one is very different from the previous one. In addition, you invite you to play in the best possible way to strengthen you.
It has a heavy character and an agile that have different shots skills (if I remember correctly, of the same category). There is a third that I have not tried.
In addition, it is a full -fledged bullet Hell. There is an overwhelming amount of shots, although dusty.
It is a game that I recommend if you like Contra.
