i had this idea for a long time, it would be like this.
a new section would be appear on the settings menu of Lost Word, it could be called "Beta" or something like that, and there, Devs will announce any upcoming update (Characters, Mechanics, New system, New stage) And as a player, you can offer yourself to be a tester of those new mechanics, with that it would be more easier to identify Bugs and things like that
