There are alot of gripes about this game, and alot of things that hold it back, but it's important to understand what you're getting into here.
First and foremost, I'll start with the bad.
The game had alot of features cut. I'm sure the developers would have liked to add advanced track editing, more songs, more characters, more anything, really. It's a game that aspired to be the best, and while it's good, it fell short of staying in the spotlight due to the aforementioned issues.
Kickbeat features something that most rhythm games don't have, especially among those that try to bend genres to include a wider audience (I'm looking at you, Audiosurf). At its heart, it's a competitive game. It's a hard game. It's one of the few rhythm games out there that has a scoring system which means something. If you can six-star a song on master, you can post a video on Youtube, and and proceed to feel good about it. This isn't a game that you zone out and play. At least not if you want to do well. At the same time, the game's not impossible, nor is it inaccessible. It incorporates a few ideas, but it doesn't make the gameplay awkward. It's simple, but different, and in this case, it works. The developers made sure that this game ran well, and of course felt good to play. What it skimmed on with features, it more than made up for with a good core.
Getting good at the game is hard, and for some people, just being able to play it is hard. Kickbeat's story mode does a great job of at least making you able to. It's cute. It's funny. It'll make you stop and ask yourself why most games try so hard with their stories.
Rating the value of a competitive rhythm game is hard, especially one that's well aged. I won't. If you play Kickbeat, from start to finish, you'll at least get 10 hours out of it, which isn't bad for the price. If you put it down because it's too hard after two, I guess I failed to warn you enough. The music selection is also one of the best I've heard in any rhythm game out there. They used good artists, and the tracks fit the gameplay well.
Lastly, I feel like I should touch on this, as it's the most important point of all. Do you like the concept of rhythm games, but feel like they're too pointless, are just for ♥♥♥♥♥♥y, and also like watching martial arts combat too intense for modern kung-fu movies? If you answered yes, I'm afraid you need to buy Kickbeat, because even with all of its flaws, this is the best rhythm game on the market for someone who doesn't want to either zone out and fall asleep, or play Osu! all the time.
