Meritous is an action-adventure dungeon crawl game about the psi user Merit. The game features 3000 rooms to explore, which are randomly generated at the beginning of the game. Your only attack against the many bullet-firing monsters in the game is by charging and releasing a circular wave of psi. When you kill monster and transforms it and in some cases any bullets it has fired at you into 'psi crystals' which you can collect to purchase upgrades to your attack charge-up speed, your recovery time until your next attack, and your automatic psi shield. Starting from version 1.2, except for music in the official version, Meritous is released under the GPLv3.
