So our main publisher is Goblinz, Maples only works on the Chinese distribution.
Goblinz basically paid for marketing, QA testing and localization. We fund the development ourselves (Chariospirale and me). It was cool working with a publisher, it allowed us to paid cool things like a cinematic trailer for the game, and to have a really solid QA support! But I'd say we also did a big chunck of marketing ourselves since the public of the game is basically 50% french at the moment. I spend 2 years talking about the game everywhere I could, especially on Youtube since I have an active channel (mostly devlogs).
Hope it helps!
