There are an awful lot of "Not X, but Y," "a testament to," "No longer just an afterthought, but..." and other AI-isms. Nothing certain, but it does feel like it, especially in some of the higher weight events.
How can this claim be completely verified other than CringeIndeed responding to these elements? Common techniques or not, there are other indicators. Markdown styling that AI often generates but isn't interpreted properly by Ren'Py is also present. I'm not saying I'm certain either, but a response denying this would put everyone at ease. This is not intended as libel/slander, but an invitation to dispel these worries.
