How to report issues and ask for support

Hi,
I have an issue when playing Hatsune Miku Project Diva F [BLJM-60527], sometime the game not respond to the key I press, it happens more often when I use controller than keyboard.

You literally didn't read the first post of the topic "reporting issues", which you are posting in, when you are reporting an issue...

Anyway I would guess the game just runs slow and therefore doesn't have the correct timing or whatever.
