I suggest us wait patiently, the time and time zone are not much different. The author either has something at home or at work, or there is something wrong with the game, so he hasn't replied to us.
Thanks for your understanding and patience; we were extremely busy during that time. We encountered several challenges, even when we wanted to release the demo. Unity kept freezing, and each time it took us many hours to troubleshoot and fix the issues, causing the demo to be released later than announced. :(( Now that the demo is out, I hope you like it and are looking forward to the official release! :3
