Finally I could check for and even finish "my own" complete game version. For that I used my existing complete/compressed Mod episode downloads as a base. It was still a "little" challenge, I had quite some game and Mod code to adapt for it.
I did a "quick skip" through it for testing. And at least I had no game errors. Some things from the early Mod version are adapted now to the latest one. Also I removed the Mod choice for the random game elements in the first episodes, you get now the best outcome anyway.
Be aware it's still a test version, there probably are some bugs left in it (let's hope not to many). The game size is surprisingly small for the combined download (~1GB), probaby because the game has no animations.
Therefore I most likely will try to do a port for it, too Edit: Android port is now also available
I also left my saves from the testing in the download (only for PC), on save page 17 and up. They are made at every start of a game part from all episodes.
