Nice game. I also took the "play the map instead of player" with physics too.
Like IrrelevantGaymer says, you include all your sources in the build, and .git, etc... So build your project in a 'builds' dedicate folder, then zip all the content except XXX_BurstDebugInformation_DoNotShip. And if you can, make a WEBGL build, you'll get more feedback.
Other than that game was fun to play. Some sound effect on collision would be welcomed. Nice music.
Great job.
