The gameplay's good if not repetitive without much of a hook beyond the first couple of levels; The music is great and fits very well with the game's themes; The story sucks because it's just there to give you a reason to shoot shit to a beat, and lastly the game isn't very visually appealing in a lot of areas though it does have its moments in later levels. That's Hellsinger in a nutshell, it's probably a 6/10 (3 stars) for me mainly because I set my expectations too high due to the Steam Next Fest demo being so memorable, it just didn't provide anything new beyond its base premise.
