Billed as a tough-as-nails boss rush shooter essentially, that description is absolutely accurate. The problem, to me, is that even in the "Tutorial" while you're trying to get an understanding of what's going on the game is determined to destroy you with enthusiasm. This approach of "all stick and no carrot" might have an appeal to a subset of the audience but mixed with the limited power-ups that also then chip away from your time (once you run out of time any hit means it’s game over), not even yet understanding the big picture, it’s a perplexing choice. Mix that with the shooting action and visuals actually being a bit on the dull side (just designed to be hard, but not exciting) aside from the need to conquer something hard for its own sake this is a tough sell as there are many more rewarding and still super-tough shooters out there on the system already.
