frustrated PC player

Why are there zero options for a PC user to simply use the space bar to jump? I have attempted and failed so many times that I cannot hate hate hate this mode any more than I already do. I have completely finished beast yeast on hard, have finished Timeline of fate on story mode and have started on the hard mode.... as for Crispia, I finished dark and hard mode through chapter 16 but I have been stuck at this stage for over two weeks unable to make it through this gauntlet that is intended for phone users as if their phone was a handheld game system yet zero ways for a PC user to adjust the settings to allow for PC favorable gaming.

The only thing I can think of is to allow my child to do this for me on phone (I cannot as my eyesight is poor on the phone.) I am so frustrated by this as it is preventing me from getting any further in Crispia.

Am I the only visually impaired PC user struggling with this D-f slide jump stuff?
