so fun! the thing that messed me up the most was switching between regular and inverted controls. it was easy to switch to inverted, but not back to normal!! reset levels sooo many times because i wanted to go up with regular movement but auto-hit d.
i suspect the comments about input not getting recognized are because the movement/input speed is just very slow (or was for me). once i started pacing my inputs none of them were missed. however i think a faster pace would be nice (maybe as a hard mode?) because the slower pace forces you to think more. i think if you could move as fast as you wanted, there would be more room to screw up, and *you* would have to get yourself to slow down.
but maybe i'm wrong and i just got lucky with the inputs.
