I'm also having the issue of several .png files not being loaded correctly and the game displaying a black rectancle box where the sprite animation should be.
I have it with mom standing still, "$mom_casual_idle%(32).png"; as well as the son character moving "$son_casual%(32).png". Probably more but I'm not continuing playing this until this quite major issue is sorted.
EDIT: I 'm playing on linux by transfering the game files to a native linux NWjs. I don't think that's relevant for this issue, though, as several other people have reported this issue as well on windows.
Probably to do with case sensitivity. The game is trying to load "Image.png" but the game directory has "image.png". On Windows that's the same file, but Linux is case sensitive so it fails. I used to get that a lot when playing on Linux with native nwjs binaries. I get around it by using casefolding on ext4. This will allow you to mark certain directories case-insensitive, and games will just run without a hitch. Also fixes a lot of other games that just behave dodgy. Read more how to use it here:

I'm on a steam deck, and if I remember correctly I enabled casefolding by doing roughly the following:
- Drop into a rescue shell to unmount your main partition
systemctl isolate rescue.target
- You probably need to login again at this point into a text shell
- Enable casefolding on your home partition (which is ext4)
tune2fs -O casefold /dev/nvme0n1p8
- Reboot into the full OS
systemctl reboot
These steps are specific to a steam deck, but if you know anything about linux you should be able to use them on your own setup. After that you still need to set the casefolding flag for your porn games directory, and you
must COPY games into it, not move them. The flag is only inherited by new files, so moving a directory will not give it the casefold flag. lsattr is your friend. Also
this is not at all guaranteed to be the exact way I did it. I'm just talking from memory. None of these commands are dangerous but know that you're just following a random stranger's internet advice. If you don't understand what the commands do don't run them until you do.
Good luck.
EDIT: ok lmao just saw your edit. So this is probably not going to fix it. But it'll fix a lot of other broken NWJS games on linux! So I'm leaving it up. One of these days I'm going to make a proper thread with all my Steam Deck/Linux tips and tricks for playing porn games.
