It's essentially a game making fun about death, religious hypocrisy, and materialism. It plays as roguelike Legend of Zelda (the first one).

...I prefer "Enter the Gungeon" myself - better mechanics, all enemies are based on puns, and a better homage to older games. (Ganondorf? Meet Cannondorf!)
...Or Titan Souls, which is an awesome one-hit-you're-dead game with a variety of boss battles.
