Who else has this game? Anybody? No.

Those who don't should go out and get this game immediately. Then share your high scores (even though it has leaderboards) so I can fail at beating them.

This is my favorite third-party game right now, and a completely badass rail shooter. I've gotten more out of this then SF643D (partially due to the fact that all the content of that game is recycled). Awesome graphics (even beating titles like Kid Icarus and Mario 3D Land), plenty of content for the price (I got it for $3, but $20 makes perfect sense), both types of gameplay (single-cell ground and rail shooter) are engaging, I don't know how much I can recommend this title or the eShop version.

Just a fair warning to others, if you're not into high-score chasing, don't get this. I beat it in about 3 and a half hours.
I'm into chasing high-scores, however, so I had a good time with it. The leaderboards are pretty empty, though.
I'll post some of my crappy high scores for you later, @rayword45

I've heard people go as low as 2 housr. But this is the best 2 hours you'll have when it comes to 3DS shooters (outside of Kid Icarus). Plus there are the missions to add a bit of time.

If you're not into that but can find it cheap (say, $12 or below) then get it.

@rayword45 Actually, it's probably better for others to just wait and get the improved eShop version at this point. More content, a pretty cheap price right from the get-go, and circle pad pro support all make for a better game. There will most likely be more players too, which means more consistent leaderboards support.
