You can totally play it on linux, an easy way is to download the windows installer, unzip it, download lutris, add the game as locally installed, choose wine as the runner, select the .exe file as the executable et voila!
Run it with Wine, or install the Ren'Py 7.4.11 SDK, copy over 'renpy.sh' from the SDK to the game directory, rename 'NEET_Girl_Date_Night.py' to 'renpy.py', and execute 'renpy.sh'.
