To be honest, its not very good. I agree with the other review, it kind of leaves you feeling like a waste of time. The game doesn't do a very good job of explaining the controls and basically requires you to always take the first couple hits on your run as you try to figure out what it wants you to do, since there's no explanation at all aside from what you intuit. That's already been talked about extensively though, so I'll refrain.
Another thing to point out is that having a system that requires you to completely restart the game upon a loss is a BAD combination with unskippable cutscenes. Making you restart for such a short game isn't a HUGE deal (but it's kinda lame with how unvaried the battles are) but if you do that you need to let the player skip the unplayable segments.
I'm also kind of baffled at the decision to make the final boss a simpler and easier version of the previous fights that's purely just more tedious because he has a bigger health bar.
