I have mixed feelings about it. I definitely don't think it's Double Dragon. The thing I always liked about the first game in the series is how grounded and minimal a lot of it seemed...well, in the original arcade version, anyway. Like how the leader of the Black Warriors was a guy with a gun. Or even how one stage just scrolled into the next, making the levels feel like one giant set piece. And you could've never known about the post-apocalyptic back story by just playing the game itself and nothing else. To me, the game just had this simplicity that really gave it its charm.
Neon was the exact opposite. It's just so over-the-top in everything it does. Also, the game stopped being Double Dragon after the first level or so, and just became something else entirely. There are cool little nods to the series thrown in (like the ceiling spike traps or the huge tank thing from NES DD2), but it kind of reminds me of how Lords of Shadow had references to the older CV games, but in name only. It was kind of neat, but frustrating at the same time.
But I'd be lying if I didn't say the game was totally fun. I had a blast playing it, and I'll probably do it again on a higher difficulty. I didn't like how sluggish the run function was, or how the cyclone kick wasn't its own separate move, but everything else about this game was pretty solid. The whole 80s feel to it definitely brings out a sense of nostalgia for me, too. And I also liked having unlimited continues, but restarting a level when you lose your lives; the way they did the whole lives scheme in this game almost made it seem more...fair than other beat-em-ups, I guess.
So yeah, it really wasn't the Double Dragon revival I was hoping for, but it's a pretty awesome game regardless.
