I've put in quiet a decent amount of time into this game at this point and figured it was about time to write my own honest review of the game...
As a tl;dr for anyone not looking to read through this entire review before buying:
I give the game a 6/10, I'll give it a thumbs up because it's enjoyable enough, but I don't necessarily recommend it. The game itself isn't for anyone and if you're planning on buying it, wait until its $5 or less as the $10 price tag is too much for this game.
The game itself is exactly as it claims it is when it states that it's "a music reactive Platform Racing Game". The game itself is centered around competing against other players online (or against your own times) while avoiding obstacles that are Somewhat
reactive to the music. But this "reactive" element is where part of the problem I have with this game arises. Depending on the song currently playing, certain elements of levels can be virtually impossible to complete. As songs get more and more upbeat obstacles seem more aggressive and unpredictable. Be it those strange "bass" obstacles that send you flying away from them, the pulsing buzz saws, or those obnoxious cannon like things, certain songs will make these obstacles about a million times more difficult. I myself would often find myself waiting for the brief moments of peace at the end of one song while another was preparing to start before trying to quickly rush through an obstacle I'd been stuck at for what seems like ages.
Next up, level design. While all the stages themselves are unique and different, there's a few major problems I've noticed in levels that just makes the game itself incredibly frustrating to play sometimes. On some levels you'll get a checkpoint nearly every 20 feet, so a death is meaningless and can cost you only a few seconds, while on other levels I felt like I'd spend a minute at a time avoiding obstacles only to die and be sent right back... And that without mentioning some horrible level layouts where I could miss a jump, fall down for about 15 seconds and land on a platform near the beginning of the level, forcing me to start almost the entire race over again.
Multiplayer itself seems to work well enough, however I haven't been able to play much online. Half the time I can't find a server with anyone to play against, and whenever I can, they'll often leave before we can even pick a level or make it any significant distance into a race. However racing against a friend while chatting over skype can be a blast.
Overall the game itself isn't bad... but I wouldn't by any means call it great or even necessarily good. It's a basic platformer, with controls that can be a little bit slippery, beautiful background images, and a diverse and enjoyable soundtrack. While I wouldn't necessarily recommend the game at full price unless you're really really itching to get your hands on it, I would recommend it if it drops to $5 or below. And at that point you may want to grab a 2-pack so you could send a copy to a friend if you ever wanna play a quick game to pass some time.
