Imagine a fast 3 way road/track full with coloured blocks that you need to hit as many as you can. But there are also grey walls you can crash on to. You can't slow down or take a break.
Imagine that track changing every single song you play, no track is ever the same, only if you ride the same song!
The differences are not predictable. Trance songs always create challenges, being one of the (or even THE) hardest music genre/style to Audiosurf on and to finish your song without crashing a grey wall, and not missing more then a couple coloured blocks, with no blocks left in the rows.
You will be able to breath in the break of the song. If the song has one.
And you will be shocked when the tune drops after you just caught your breath...
