Weird. Unfortunately Ren'Py's web export is only in beta so it's not fully supported and is occasionally problematic. But I've only really encountered problems with Webkit browsers so far.
Did you play the first two games? If so, did they run okay?
Was just looking into it and apparently Chrome 100 did something that made Ren'Py web games unplayable. It's reportedly working again now with new builds, but I'm going to have to re-build and reupload everything . Which I will do as soon as I can.
Thanks for bringing this to my attention, appreciate it.
