Huge refactoring needed.

[Unengine]

Currently my code is so dirty, hard to read and has poor scalability.
So, i will refactor my code later.
Since i am so busy, the 'later' can be some months later, or even be some years later.
I'm going to use UniRx to refactor my codes.
So keep in mind that my code is a really BAD code and going to be hugely refactored.
If you want to contribute or study with my code, i recommend you to focus only on game logics, not the structure.

Good codes that includes the game logics

BMSHeader.cs

BMSMultiChannelAudioSource.cs

BMSObjects.cs

BMSGameManager.cs

• important but async logic is so bad.
