And also why use a .dat file? no need to answer that question but i'm interested in why its used over just normal sound files.
To be honest I'm not quite sure. I've noticed sound always seem to take up a large chunk of the project, but as to why the .dat format I will have to admit that I actually haven't looked into the details of audio that much.
What I can tell you is that I think the music tracks are quite large, and were uncompressed as .WAV when I added them to the game. The game is made with Game Maker Studio 2, so maybe their audio system turns it into .dat for reason. I do not know!
Thanks for checking out the game!
