Ideally, by the end of the month, but I invite you to stay tunned on my patreon, I will reveal things before the update :)
Honestly, I'm still exploring the most efficient way to monetize the game. The goal is to find a balance between creating a great user experience and generating sustainable revenue that will allow me to continue developing the game, ideally on a full-time basis. For now, what I can tell you is that there will always be a free version. I will also have an early access version available for my Patreons, which I could also offer here for a couple of dollars. I haven't ruled out the idea of releasing the final version on Steam, but that's still a bit further away.
