Players based in China may experience issues with text-to-speech playback.
We use Google Cloud for text-to-speech services. While our Google servers do not explicitly block China, we can't speak for the reverse.
Google states: "If you are hosting a website on Google Cloud, traffic coming from the China users will not be blocked. That being said, Google does not have any control over the GFW blocking methods."
Any text-to-speech errors might be due to your return connection through China, which is out of our hands. Since we aren't able to accurately test connections in China, there's not much we can do at this time.
If you need a refund, here is a link to our return policy: https://widerightgames.com/tos.html#return-policy
Sorry about the headache, but this is one of the reasons why we don't officially sell the game in China.
