Hey! I'm getting the same error code as some of the other people; the screen with the "attempt to index a nil value" message and then getting booted to home. I re-downloaded/re-installed a couple times to make sure, and couldn't seem to fix it. Just fyi! Looking forward to playing:)
Hey, thanks for bringing this to our attention! It looks like Panic's sideloading servers are broken right now so the files aren't downloading correctly. USB sideloading should work fine though, in the meantime. (https://help.play.date/games/sideloading/)
