"Infuriatingly difficult, but perfectly constructed. Ikaruga is the PC's best bullet-hell shooter."

Great Game , runs really smooth. I do notice framerate hiccups of 1 frame of animation now and then but it's nothing to complain about. This game is really friendly for anyone who is new to the genre of bullet hell style shootings as you can turn on Free Play from the get go in the options menu of the game and play with unlimited continues. You can even modify the lives you can start with and more. But be aware- if you modify certain options other then the default setting you don't qualify to have replays saved or your high scores saved - it will simply say not available. I guess this is to deter people from unfairly getting good scores in the Free Play (unlimited continues mode) . But it helps newbies learn the game mechanics with a no pressure system. And it's only 5 bucks during the Summer Sale so there is no reason why you should not get it.

Now if only Trigger Heart Excelica and Radiant Silvergun could get released.....

With the additions of leaderboards, replays and higher resolution support, this is definitive version of the Arcade, Gamecube and Dreamcast bullethell classic.

If you have any interest in the genre, pick it up. I promise you that you won't regret it.

Ikaruga is a diamond- beautiful, and also REALLY REALLY HARD. The difficulty is probably discouraging for some, but for players who enjoy trying again and again and feeling the improvement every time they try, this here is top tier. I've worn the Ikaruga as my internet face for ten years now; let that be testament to how much I love this game.

I mean, I'm awful at it. But I love it.

I first played Ikaruga for the GameCube and instantly fell in love with it. At first I treated it like any other shooter before I even started learning how to chain combos properly. The combo system is where this game really shines, it turns from a "shut your brain off and shoot enemies", to a fast paced twitch puzzle game. I've spent countless hours on the GameCube version of the game and the PC port holds up well. When you get into the groove of the polarity switching and memorize enemy patterns there really is no limit to what you can do next to improve your score.

What kept me playing is i never felt like I’ve hit a plateau in what kind of score i could achieve, there is always positive reinforcement to keep playing because you can see what the guy ahead of you on the leaderboard has done... don't go way above your means and watch the number 1 player and think I’ll never be able to do that... watch the guy who's only 2 million points ahead of you and mimic the style he's using... you'll quickly learn that the game that's touted as "impossibly hard", is actually very doable to get a high score.

I recommend giving it a fair chance turn the BGM off and play some of your own chillout tunes and enter the meditation that is Ikaruga.

-very forgiving hitbox often times you feel like "how did i just survive that?!", rather than "oh man how did i die there!?"
-mesmerizingly intelligent level scripting.
-intuitive design
-perfect integration of the Microsoft controller, and also very good response when linking a ps3 controller via 3rd party apps.

-no longer has slow mo, and training that was included in the GameCube release.

This is a classic shooter that's hard but fun. Unlike the Gamecube version, you can have unlimited credits. The 360 controller works nice with the game. I paid $5, which was less than I'd spend trying to play it in the arcade.

If you like hard shooters and want more arcade shooters in Steam, support it.

After roughly 4000+ hours in this game over all the console versions. I still feel like nobody ever quite explained it as well as Greg Kasavin did, so here's his review. Notice this is the GameCube version he's reviewing, and all versions have very slight differences, but the XBLA version added the most "features" so to speak, and that's mainly what we got with this version. It fixed a lot of things the XBLA port got wrong from the arcade and DC/GC versions. My only nitpick is, they didn't include online co-op which the 360 version had, which hopefully they'll patch in at a later date. And there are people who have latency issues with the game at the moment so hopefully that's fixed fast. I also really hope Treasure VAC protects the game at some point as well. Another sad thing I guess is, the previously announced Trading Cards are now no longer happening, apparantly, the store page isn't even listing them anymore even though Treasure themselves confirmed them...

So, best review of the game ever -

Go buy it!
