It is planned but require way more work than 2 legged ones for now. As it require a whole new set of animations for the visuals, and I don't talk about the potential consequences in gameplay of not being able to reach the top of the chauldron :D
Discord server is indeed something I planned for the release of the Alpha but might be done before if the community ask for it.
The player character has no gender as I wanted everyone being able to identify to it. Character customization "might" happen, but it's clearly not a priority right now.
