Thanks! But yes I'm a bit confused... In my Compiled folder I've got my compiled game. In my Windows folder I've got my compiled game. In my data folder I've got some of my compiled game... And what is that game.ags file? Are you saying that .ags file needs to be distributed as well? It's not in my standard Compiled folder or my Windows folder though, just the Data one. And where should I be taking my game files from? I'm taking them from "Windows" currently and ignoring the root Compiled folder. (admittedly I might have copy+pasted the contents of windows to the root folder myself)
Ok, to elaborate.
Before 3.4.0 the structure of files in Compiled folder was very simple: only Windows version, made as bundled exe.
In 3.4.0 the Compiled folder itself keeps intermediate output which includes non-bundled "raw" game data, usable with any port (including Windows), and Compiled/Windows folder includes specifically Windows version.
In 3.4.1 we cleared things up by moving unbundled data into Compiled/Data, and Compiled folder itself is supposed to stay clear of any files.
I.e.:
* Compiled/ -- no files here, only subfolders
* Compiled/Data - raw game data, usable with any port if you add port's executable. Also, you may add some custom data files there, and they will be copied around to Windows, Linux etc versions.
* Compiled/Linux - game data combined with Linux binaries
* Compiled/Windows - game data bundled with Windows binaries
All this is explained in the manual, BTW, the topic is named "Distributing your game", also may be found by keywords "Compiling the game".
If you have upgraded your game from 3.4.0 to 3.4.1, you may have old files remaining in just Compiled folder that you can just delete. Unfortunately at the time being I was not able to invent a proper way to clean things up automatically. The problem is that this folder may contain user files, that is files that user put there themselve, and moving them somewhere could not be wanted. There might be some simple way to solve this, but... perhaps in the future update.
