Bro vosmug is an OG from way back in the day before shit like patreon and the like become a blight on the H game community. Anyone who was back from the Kyrieru days, (rip if he's dead) more than likely heard of, or played Vosmugs games. They never flaunted themselves like a lot of the other Devs do because instead of just raking in subscriber cash, they go by game sales. Probably why you've never heard of them.
