4Player - "Sine Mora strives to make its mark and succeeds in not only doing so, but also in firmly tattooing its initials upon it. It is a game who’s name will surely come up over and over by equestrians of the genre, and will be a superb introduction for neophytes who might have stayed away. But beyond that, Sine Mora does even more. It treats its subject matter with a maturity and solemnity that redefines with a side-scrolling shooter can be and, in doing so, almost creates a genre all its own. Within a genre that has been around almost as long as video games themselves, Sine Mora stands tall as a perpetuating knight, carrying its banner into the next phase."
