ULTRABLIGHT is becoming ENFER
Hey everyone!A few small but important updates:First — the game is getting a new name. Over the next few days, ULTRABLIGHT will be renamed to ENFER.The main reason is pretty simple: the old name had too much overlap and potential conflict with existing brands and other names. I'd rather deal with it now than turn it into a bigger problem later.The game itself isn't changing — just the name.Second — the Discord link has been fixed! Thanks to the players who pointed out that the old link was broken. The Discord server will also be renamed to match ENFER. https://discord.gg/tPwcUc8YpQAnd finally — I'm starting a dev blog. I'll be posting regular updates about development, new content, mechanics, enemies, items, locations, and whatever else I'm currently working on.So if you're interested in seeing how ENFER develops behind the scenes, stay tuned.Thanks for following the game — more soon!https://discord.gg/tPwcUc8YpQRead full article on Community Announcements (Mak)AnnouncementsOfficial
