This was something I had on my idea box for a while, but I managed to implement a custom package system based on Google's Brotli compression. Basically, the game will decompress the game's files once on a safe location and the game would load the decompressed files. Compared to the current builds, the game doesn't have to decompress the files every time it starts up. All I need to make sure is to patch the files when the game is updated.

Maybe, at some point, I could add online updates. But that's a bit of a "pie in the sky" idea.
