I made a pong game, and I’m pretty happy with it, but adding sounds and music alone almost puts the game past its size limit. Is there any way to bypass the file size limit for future projects, or am I stuck with the 10 megabyte cap?
Here’s the project link: Gravity Pong by judah.lewis | Snap! Build Your Own Blocks
Unfortunately there is no way to bypass the file size limit, so we all are stuck at 10mb. But some ways you could decrease the size of your music is split it up. If there are any continuous loops (take the title screen of Super Mario Kart for example), you can split it up using a video/music editor. Then, you can upload the separate sound files. You can then program it so then it plays the intro notes, then forever play the continuous loop. That is how I (somewhat) was able to stay within the 10mb file limit.
The 10Mb limit applies to the project as stored on our servers, not the size of the project once it's running. So people with media-heavy projects typically store the media somewhere else (or just remember where you found the sound in the first place) and use the URL block to load the media when the project is first started.
What’s the name of the song?
Ok thank you 
Gravity I think
You can also compress the file using a file converter. OGGs and MP3s are dense (meaning they take up less data). You can also change the file format of your costumes so they save a bit more space.
