247MBs? That is optimized MV! :D
I wish I can be that efficient one day.
LOL! RPG Maker MV gives the devs approximately 200 animation sequences with all of the art and sounds preset. A lot of space can be saved by removing them from the game prior to roll out, and removing the .m4a files when not doing a Mac or Android build.
I should ponder about it ^^ LOL awww... My bro have nice music all .MP3 but... I think it is easier to convert into .ogg but... well MV. Yeah each time I open a new project it is already 1gig XD so something has to go LOL
