2.3gig to to 1.2 actually, but lets just say that if i wouldnt do any compression at all and just put all the images in the unity game, it would result in a game like 20 GB at least, it was already going upwards 8GB when i was devtesting first version of 0.4.0Not sure what you are asking, but v0.5.1 is already compressed. Switching from png etc. to webp reduced the game folder from almost 3GB to 1,2 GB.
In general all Unity games are compressed and any further compression is not possible as you see for Ren'py games.
Actually now its animations that are catching up on the game size now. I can maybe manage to shave off like 100mb or 200 from some files eventually, but right now it's really damn compact for what it is. There's a lot of stuff in the game for that size.
