The developers behind LICHTSPEER recently held an AMA on Reddit. One user asked about online rankings, and in the answer was a very interesting quote regarding achievements coming to the Switch.
Nintendo doesn’t have an official support for Achievements and Leaderboards, like Sony or Microsoft but we know that they’re working on it.”
This seems like a statement based around some form of prior knowledge. With Nintendo delaying their payed online service, it seems as though an achievement system is in the works!
