You really should consider putting this beauty on Steam, especially with itch changing their payment options (or so I hear)
There are a TON of games on Steam which look like *expletive deleted*, and are only a fraction into as much development as Eternum... and another reason: I can buy Steam cards, so I don't need a credit card or paypal or whatever... I'd buy in a heartbeat... and maybe add the content for patreon in a DLC or something?
