Hello!
Thank you for appreciating the graphics, I really did my best not being a modeler myself. Concerning the game mechanics, the comments when looking at items can help in finding out the right song, of course you may need a good knowledge of the music world but I think it's not that hard! About the last two things, I'm thinking of getting an in-game system to pick the songs so that you don't need to rely on your own drive..the last one though seems to be quite hard to solve. I wonder if gameplayers who play AudioSurf with their own songs have this problem..probably it is allowed only for non-monetizable videos.
Thank you again for posting and for the interest in the game, glad you tried it!
