I am Lu, a game developer. I’ve created various works on my own as an indie.
Sometimes I look back on my life.
It hasn’t been a smooth or fortunate journey.
…In the end, I gave up on everything.
Video games—
and every other path as well.
But I have to express myself.
Through video games.
I have to dedicate myself to them.
Through video games.
That’s why I have to keep going.
And there’s no escape.
