oh no! if you could please show me a screenshot of the problem and let me know which one you downloaded for (windows, mac, etc.)? you shouldn't have to download Ren'Py to play, but i'm working on a bug fix update right now. hopefully it'll fix the problem. please look forward to it! thank you thank you!
i also, only have a macbook so i mostly rely on friendly people like you to report bugs to me. thank you for bringing this to my attention! C:
