KickBeat is a rhythm game that's almost good, but doesn't quite hit the mark.
For starters there are only 24 tracks, and they're pretty much all either what wikipedia defines as 'Industrial Rock'/'NuMetal' or the 6 electronica/dance tracks by Electronic Super Joy. This ultimately leads to a pretty low amount of genres. There is an option to make custom tracks out of your own songs, and while you can set the BPM, you cannot add true custom tracking as far as I can tell, leading to a sub-par experience there.
As many other reviews have noted, the notes don't really match up with the rhythm that much, so you will primarily be relying on the visuals to know when to press buttons. This leads into another large flaw of the game - the visuals are incredibly noisy, often making it a strain to know when the 'enemies' are coming.
Another mechanical quirk of the game are the 'power up' orbs. These primarily just give you bonus points or multipliers. There's also a shockwave (clears nearby enemies) and a shield, but using those actually grants less points than not using them. The quirk is that you have to doubletap the button in order to pickup the orb. On the higher difficulties, missing an orb counts as getting hit. This is problematic because it can quickly grow incredibly tiresome to doubletap orb wielding enemies in succession.
The game was initially designed for consoles - as such I used a controller for it, but that brought its own slew of problems. On expert/master difficulty, there are often enemies coming from three directions. As almost anyone who plays on a controller is aware of, pressing an opposing pair of buttons (example: A+Y or X+B) on a controller is incredibly awkward. Combine this with needing to doubletap, and getting punished for hitting extra buttons, leads to a frustrating setup. I imagine this is much easier with a keyboard, but it does raise the question of why the game was designed this way to begin with since it initially launched on console.
Finally, I just wanted to point out the silly unlock system the game uses. You're stuck with playing as the male character until you complete the game's story as him - then you can use the female. Despite being given seperate 'stories' they both play the exact same songs, and have the same gameplay.
Oh - right, this game actually has a story. It's, as to be expected, absurdly terrible. This isn't a problem in itself, except for the fact that there are a couple brief unskippable cutscene parts associated with the 'boss battles' which are painful to sit through.
Anyway, despite all my whining, I did finish the game - which is saying something in itself. There is potential here, and if you picked this up in a bundle, it's worth giving a whirl. Ultimately however, I cannot recommend actually buying this game by itself.
