Ninkmi is a brand-new mobile rhythm game that is still in development (which is not free).
Since this work is still in the very first part of development, I don't know. If you are curious, check the news, if any information is updated, it will be shown there.
For now, I only accept people who can go to Gongguan(台北公館) often to meet me in real life, and must better be university students. I may consider letting more people to join my team when the game is stable.
If you are really willing to make a rhythm game with me, feel free to contact me no matter what your major is, I'm welcoming for people who can join my team now!
