Yes. I remember when they doubled it to 20mb and we thought that was an amazing bump at the time, especially given how much of that first 10mb was typically taken up by the executable We always make sure to target our games at sub 50mb, so the new limit hasn't been much of a problem for us. I can see it getting harder and harder though.
Yup, 1 main menu song, 5 played randomly, 1 "boss" level song and 1 for the final cut scene. Made sense at the time... now... not so much
