An addictive and fun casual game...
Another problem i've come across is that some tracks wont really play like they should do and you'd think it would be a fast paced song but you're sitting on a slow hill the whole time, it can really ruin songs and make it not fun to play. I wish they did something more to make slower songs fun and wish they'd fix some stuff to make other songs play properly.
The graphics are nice to watch and great and the sounds are great, obviously this mostly depends on your song though because that's all you will be hearing for most of the game. The menus are all great and everything controls really well and found it weird that you use your mouse rather than the keyboard but it makes sense when you're playing because the reaction time when using the mouse is much much faster.
So yeah for $10 Audiosurf is a great little casual game purchase and you wont regret buying it, quite weird how this style game could be sooo fun but that's just more props to the developers for making this game. Turns a simple idea into something sooo addictive and fun.... I just hope some of the little annoying bugs are ironed out soon and they carry on adding features, though for $10 it's hard to imagine they'll add much.
