Newest bullet hell shooter I played on kongregate: Red Fluxion!

Unlike some popular bullet hell shooters, Red Fluxion is fast paced, challenges you, and isn't afraid to make you wonder if your computer can handle that many bullets. Sometimes it feels cheep, and you'll wonder if that boss's attack can actually be dodged a bit too often. And, as with Pixelvader, anything but bosses sometimes feels like a waste of time as you quite effortlessly eliminate hordes of munchkins by superior firepower alone. But is it fun? Yes, and that's all that matters. It's not the most fun I've ever had, but still worth playing.

While beating the game isn't that hard, the game's grading system challenges you quite a zetta bit. Now, some of it seems unreasonable (beat the level without getting hit? Psh!), and the fact that some letters get assigned a "-" but not a "+" and vice versa is irksome, especially since some important landmarks are missing (don't lose any lives gets you no better grade than losing one life). However, the simple addition of an object that tracks and displays your average grade actually gives you a push for a better grade. Unfortunately, there's no gameplay reward for getting a better grade. You only get 13 factoring skill points, give me another for getting a factoring A-!

Speaking of which, I did like that the upgrade system didn't let you get every power up the way Pixelvader's did. You actually have to implement strategy in what upgrades you choose, you can't say: "Oh, I'll get that upgrade later," or something ridiculous that ruins the game's difficulty.
