Why can't people just fucking merge the entire thing into one singular fucking download ffs? What is the point of all these downloads, merging, copy here, paste there, bring here, open with this, download that, add game here, in this folder click this then hold alt as you press this. WTF is this shit? Just spent half an hour trying to get this shit to start and all images are broken.
First world problems.
Jokes aside, that clearly is the nice way to ask for some help. Specially when a game is free and still being delevoped. Anyway, I'll still be nice, unlike you're being towards the dev. Just unzip the qsp folder. Inside that put the "girl life" folder, and inside of that one put the image and sound folders. Can't be more direct than this.
The mods are a bit trickier, since some request the image and sound folders inside the mod folders, which are still inside the "girl life" folder.
Think of this way:
Folder with the qsp
--- qsp exe
--- folders of the qsp (you can ignore these)
--- folder girl life
------Girl Life 0.8.2.2.qsp
------sounds
------images
------mods (in case you want any)
---------sounds
---------images
---another random game folder that also uses qsp
------replicate above
etc...
I use qsp instead of sonnix, but I guess it's basicly the same. The player will detect the folders and files as long the image and sound folders are on the same folder as the qsp file. Anyway, if you read the damn guide instead of being rude maybe you would understand it isn't that hard to do it.
