errorlog.txt should be at the root of what’s visible when Playdate is connected via USB. I’ll have a look — I checked the game only on sim. (If the game crashes with e0 error, that’s a OS level crash and that probably won’t produce a log. But all e1 errors should be logged there.)
(Btw solid art and what a nice game! Can’t believe it’s your first experience as a team. Great work!)
