Added account system, chat and dark mode

IT'S OUR FIRST BIRTHDAY 🎉! One year after the initial public release of Werewolf Online, we are happy to present you the changes of our anniversary update. It's one of the biggest updates yet. We finally added our account system and provide the possibility to login via your NextGlobe account. A dedicated account management website to change your global username and profile picture will follow soon. After logging in, you unlock a highly requested feature: the dark-mode. Now you can finally relax your eyes during the next game night. But thats not all: We also added a chat! This allows you to chat directly in-game without having to use a separate program. In the next updates, more chat features will follow - for example "Werewolf messages" (messages only visible to your Werewolf teammates). We made massive changes to the client (the "app" so to say) and drastically improved stability - but as we changed about 70-80% of the internal core, it may be possible that there will be a few new bugs. But don't worry, we will fix them as soon as we notice them or you report them (feedback form/email/Discord)!
