Uhhh I haven't heard that report before. What version of the game are you playing, and which system?
Hmmm. That sounds like maybe the download got corrupted somehow, or things aren't loading in fast enough on your phone. I have no idea how Renpy's Android compatibility actually works, but I wouldn't be surprised if there were brands, models, or specs where it falters. Never heard of that error before tho tbh, I'm not actually sure how to triage it.
