Any chance of anyone giving me some coaching or tips? Using Japanese

Hey everyone, I don't know if asking for coaching is a thing in here, but I can try I guess.

I'm playing Japanese and having some issues with resource management and frankly, build order and stuff. I can go to Feudal quite fast, but then I get stuck there and don't have enough resources to do a flush, or actually resources at all to continue advancing and I drag behind everyone else.

I don't consider myself a good player by any means so, don't be afraid to over-explain things.

​

THANKS!
