Meritous is an action-adventure dungeon crawl game now ported to Nintendo Switch by nop90. The game is a cross between a top-view dungeon crawler and a bullet-hell shoot-em-up. In it, you control main character Merit, who travels through an enormous 3000-room labyrinth, the Orcus Dome, in order to find three artifacts called the PSI Keys, and restore them to their proper locations.
