I've got a similiar tool that I use for work purposes... my feelings on using it with drod are sort of wishy washy.
I completed the game without using any macro recorder, but I admit that now I do have shortcuts for "
qw"
and "
wq"
... to prevent accidently hitting "
qww"
halfway through killing off a swarm (I tend to do that).
But recording longer sequences, like how to navigate a whole section of tar, seems to undermine some of the gameplay. Still I know exactly how frustrating it is if you repeatedly die at the same place far into a tar maze.
My take on it is, do what makes playing the game fun for you
