Hi Julien,
We hope you're doing well. Could you try to redownload and sideload it again? We tried to resolve the bundleID/pdxinfo error but cannot check on our end since none of us own the device
Hi! I just tested it and it now works! It sideloaded correctly. When I launch the game it says "warning", with an empty box underneath, and I have to press A to launch the game, first time I saw that on a Playdate game.
But once the game is loaded, it plays correctly, I managed the roots all the way down!
