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 0.4.0
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.
