You could double click on the executable directly and see if that helps. I believe the log will be ~/.local/DroxOperative/User/log.txt which should have some useful info of where it thinks various directories are.
Depths of Peril, Kivi's Underworld, Din's Curse, Drox Operative, Zombasite, Din's Legacy, & Drox Operative 2
