This is an unofficial Pokémon dungeon crawler. You play as a Pokémon in a world after humans. You get a dungeon delving class (cleric, fighter, magic-user), you get a backpack, a weapon, and you head out on an adventure.
This game plays similar to OSR-style games with a d20, roll-under system. Most rolls are player-facing; Players roll to attack and to dodge while the Game Master uses dice to keep track of the various complexities of dungeon crawling.
As of now there are 20 playable Pokémon and 3 classes. Expansions can be made if the demand is high. The pdf is 62 pages and comes with a dungeon to start your adventure.
