Hello. We use a server to manage the exclusivity of account access to our game while we develop it from the ground up for our supporters. It's far from ideal but it's a realistic and necessary part of indie game development in 2023 if you want to be taken seriously. Especially running it as a small team that is aiming to be profitable. Thanks for your patience. Verification email issues have been fixed, if you're still having issue please contact me in the Discord.
