Please, put it on steam too.
I'm Brazilian, so as my country is passing thru an economic crisis games in USD became too expensive and in itch i couldn't split the bill in my credit card as i could if the game was on steam too.
And one question, you plan to support Vulkan in the future?
Yeah, but i couldn't split in multiple parcels, this is an common pratice here in Brazil (we call it "parcelamento", i don't know if this is a custom elsewere), this would bring more Brazilians into the game.
Instead Steam you could add an payment option using "pagseguro", or putting your game on "nuuvem" so it would be easyer to Brazilians pay and play and know the existence of this game.
