Hey, the game does not sideload properly so I asked some devs on discord and they said “It had a default example package name, so conflicted with something else using that package. Then build number was also 1, so it would not have actually sideloaded.”
This has happened with other games with default templates because the Playdate doesn’t know which of the multiple games with the same package name to load. (Or something. I’m not a computer guy, but heads up the game doesn’t work.) Hope this helps because Planetfall looks cool!
