No promises in the immediate future. I'm hoping to move to renpy 8.0 sometime soon, which does support it again, but it can't be hosted on itch anymore.
I know that some pirate/secondary sites forcibly convert the game to web lol - idk much about them, I think gamcore has it?
Been so long since I thought about 0.23c that I can't help much there, I don't have any of the code. All I can say is that it isn't an issue in .24, .25, or .26. Did you do any kind of save editing, or is that a vanilla issue?
