Hello!
Currently, we don't have a way to sell the game on itch, since we have a free to play version of the game. What we have is our Patreon where people who want to support our project can donate to us in different tiers that usually go from 1$ to 25$ and in return get some rewards like a special role in our discord server that grants access to channels where they can see when we are streaming our work and also, the latest version of the game (Usually one or two months ahead of the public build).
If you like our game and you want to support us, please consider taking a look at our Patreon and if you like it, support us =D
