Old-School Cool
Even if you don't like old, 8-bit games, you'll still enjoy Dark Void Zero. The jetpack is an awesome tool and is highly addictive, and there are about 5 types of guns, plus mini-weapons and power-ups like the force field.
The enemies are great, and there's one enemy that kind of looks like the Metroid creature in..well....Metroid, which might have been a secret cameo. The level design is what you'd expect.....from a ZELDA GAME!!!!!!! The mazelike caverns and secret enemy headquarters are very challenging to bypass as well.
Overall, Dark Void Zero is one of the best games to hit DsiWare. Some question the fact that Capcom is making old games on new systems(which is definitely not a problem with me). I made it to the top ten on the leaderboard, too! I bet all you more experienced gamers can get there too!
