So the other day i was playing around with how hard i could make stepmania (whilst still being possible to complete a hard song)
Result : Stepmania Vid (3mb)
(Expand , drunk , bumpy , reverse , dark)
Somewhat hard song i guess.
For others who play stepmania , i found a groovy place to download keyboard stepfiles
They got quite a lot of stuff here up for grabs – http://houkouonchi.net:8080/packs/
