All new content (mine and Ferdafs) will be in all downloads for this game.
The main download (sorted by system version) contains everything, renpy engine, game files, art, etc... This version of the game is always compressed, slightly lower quality images for major space savings (~250MB compressed vs ~2GB uncompressed).
The update only assumes you have the previous major release of the game (so, for version r4.1 (which will be the next version (whenever Ferdafs puts out the Unity content)), if you want to use only the update patch, you'll have to have previously downloaded r4.0 (or have all patch files up to that version)). This is meant to be as small as possible, so it too is compressed.
Lastly, the uncompressed patch is ONLY for THAT release of the game, and contains ONLY the uncompressed image files. No engine, no script, no game. Just images.
Most games do this in reverse. The main game is the uncompressed version, then they have a compressed version (usually hidden somewhere in the thread, and frustratingly hard to find).
The main reason I do it "backwards" is three fold:
1). I'm doing the compression, while most other games, someone on this forum is making the compression, not the game dev.
2). Uncompressed, the game is too big to unpack on most android devices. So I'd have to make and test a special different android only version of the game.(I still might have to do this at some point if the game keeps growing...)
3). My upload speed is not good. To upload the PC/Linux, Mac, and Android versions of the game to 3 different sites (the minimum number recommended by f95zone), takes me almost my whole day. Not even counting the uncompressed images.
So, the main version is small. If someone wants higher quality images, they can afford overwriting the small 250mb file with the 2GB one. If you don't care about quality, the main download (or the update only patch if you have r4.0) is good enough and will get you all the content.
