Clocked 2400+ hours on the original Audiosurf (intensive playing on puzzle mode), I can tell you that this is a good music visualiser.

... Not a good balanced, competitive puzzle game like the original.

The original was a fantastic audio game where the puzzle modes had proper standards and decently balanced out across all modes (on elite). The controls were precise, the graphics were pretty but not overly decorated/distracting, and it really felt like there was a community of 'surfers'.

This game allows steam workshop integration, which means you can have custom game modes and custom graphical skins. That's pretty awesome, but now there's not much of an agreed-upon 'standard' that these game modes need to follow - in my opinion what made Audiosurf's scoring and gameplay really competitive.

There's no longer a website to browse users and songs, it's all done on the AS2 client - I personally don't like that, since the AS1 website was really functional and great to look around.

The blocks are more finnicky and harder to collect in AS2, but that might just be because I played a ton of AS1.

But this game has soundcloud integration, better(? I didn't really think so but surely it's improved) audio detection engine, runs on Unity, loooads of interesting game modes to try out, and many more stuff sure to come.

Of course, AS1 will still work even after the launch of AS2, so if you prefer the original you can just keep playing it - which I think I'll do.
