The Messenger begins as a linear ninja platformer but transforms into a time-traveling Metroidvania adventure. Players control a ninja messenger who can cloudstep (double jump) off enemies and projectiles. The game switches between 8-bit (past) and 16-bit (future) visual styles when traveling through time portals. Known for its clever writing, smooth gameplay transitions, excellent soundtrack that dynamically changes between time periods, and surprising genre shift midway through.
