When execute game, there is only black screen and I can only hear cricket's chirping. Is someone having solutions?

wait what

i have my keys set to LA,TA,RA still i have no clue how to hit it

It's important to know that if you set an option for CONTROLS you actually give it, or at least set it possible to hit more than 2 keys at the same time if it's kind of a backbone for your game. There is no way to modify the game, not even a way to know which keys are the ones being used. No way to optimize the situation... It's all good and all but jeez do something about it....

it has some problems: No note hitting feedback. if the game gets faster you cant hit some of the notes and you cant change the controlls on the arrow keys (this is one of the main points. WTF why you cant do that?)
