I can't seem to sideload it on my PlayDate. Whenever I upload it and refresh on the PlayDate it doesn't come up. Any possibility that I can try with 1.0.2 of Celeste please?
You can find older releases on GitHub: https://github.com/hteumeuleu/celeste/releases
But I’d be surprised if this made any difference. How do you side load ? (Online or via USB)? What is your PlaydateOS version?
