When making the executable for your app, pay close attention to your file size.
When you compile your code, images, sound, videos and other assets all together, your apps can easily become quite large. I’ve seen too many games that sit in the 250mb to 2gb range. Sometimes the game wasn’t that large at release, but they added content over time and the file size grew in equal proportion. Some games need that much, but many could be done very similarly with a smaller size, if they just put a little extra effort into it.
Why does this matter? How big should your file size be? What can you do to reduce your file size?
