Update (11 October 2021):
Huge thanks to @希瓜果汁 for noticing and solving this bug!
- Fixed a bug with many unnecessary large packets being sent repeatedly when the gameplay starts. This caused the black screen at the start of a gameplay to be very prolonged or even take forever in some cases. Solving this bug also revealed a hidden feature, the game shows a waiting message at the start of a gameplay when there is delay. (by 希瓜果汁)
- Removed Room Server from the ZIP archive.
