because for some reason the devs thought it would be a good idea to partition the development. No idea why.why the game has 4 parts?? do i need to finish the 1st one and so on to understand the story?? iv never finish this game because i waited to play a bigger update of the game...hope anyone can tell me about the game status
All the files from part1 to 4 are still in the game's assets folder in compressed and encrypted WEBP files.
the only "logical" reason i can think of is they themselves have the game partitioned in their project folder for easier development. So they can tweak the part 4 without breaking part 1. But that's just blind speculation on my part.
