Hi Julien, I understand. The issue is arising because we cannot test the game on an actual physical playdate device since none of us possess it. For now, it is only playable on the playdate SDK software (it's why we didn't include the sideload instructions). We hope to some day get our hands on an actual playdate console and playtest on it so we can serve the lovely playdate community ^_^! (for now we are students and umm... the playdate is kinda pricey and hard to get our hands around)
