The song mappings are bad, The Crazy difficulty had no button variations and some song timings are a bit late or early.
It needs a remap keys option.
The only solution that I can give out for the keyboard mode is to rotate your keyboard sideways and your monitor either beside you or put it vertically and play like you regularly play osu, o2jam or beatmania.
Ahh... i love watching people going to work, getting frustrated, getting hit with a stick, getting annoyed by an elevator, and getting annoyed by waiting for the elevator... or thats just me...
