Will it be under the same name (Mystic Knight Maya) on Steam? And would it be your first game on Steam if you get it there? Your name (Mega Blue Ball) didn't appear when searching in the store the other day, so I can only assume it's because you maybe don't have content there yet?
Yes same name, and my previous game is here: https://store.steampowered.com/app/943520/Pixie_Panic_Garden/
For some reason, my developer name doesn't appear in the steam search. Try the advanced search too. But game titles do usually appear. Maybe it's because of the adult tag, I dunno, but yeah I'm already there and MKM will be released there too.
