It's pretty self explanatory. There could be rewards, like a free cosmetic at certain days or maybe Lunar+. There could also be a leaderboard. I was also thinking the main menu for this could be when you launch lunar client (Like the single player and multiple menu) and it could be with the buttons on the bottom and maybe somewhere on the top that tells you your streak. There could also be a streak mod maybe, so you can view it in game, although that is kinda useless. But yeah, I think it would be good.
