By the way, no one cares that the game now weighs 3 GB, and the upcoming update will have more than half of the current content (and of course animations)?
I very much doubt that the developer will allow this (after all, 0.6 is far from the end of game). What would he prefer? Transfer of all pictures in webp? With or without quality loss? Or simply increase the compression of JPG, as Luxee did, for example, for Parental Love 0.13 (from 90% quality to 78% quality), and received from 1.3 GB a little more than 700 MB... For example, this question excites me.
ICSTOR has excellent renderings and staging, but the quality of the final pictures sometimes is disgusting, and this applies not only to dark images, where the weight of 1920x1080 renders with characters is just 46KB-100Kb. Soap and soap...
With all due respect to the work of developers, of course.
