You need to look into learning something like Shotcut for your video files. Rendering these out as gifs is expensive as HELL storage-wise. You're averaging close to 7MB per gif and cutting a mp4 with audio of the same length and a larger resolution (1080p compared to the 600x338 you used) was only 4.4 mb. Dropping it to 720 made it sub-3MB.
Aside from that, I suggest replacing those AI images even if they're not 100% what you envision when you're thinking of characters and locations. The location images are pretty tacky (although you might be able to get away with some of it if it's heavily blurred backgrounds) and the NPCs look bad.
Thanks for the feedback, I appreciate it.
On the other hand, I unfortunately cannot replace the GIF with a video using shortcuts, as I did in the prologue. This would miss the point of the girlpack, which allows you, the player, to change any image you want. I wanted to do it in the beginning, since, like you said, it does save more MB and better quality, but the video code in Sugarcube doesn’t permit me to do so, since the videos need to be in a folder.
Now, maybe if someone knows how to do it, I will gladly do something about it.
For the images, those are temporary cause I agree, it does look like shit.
