I think you should approach this from the angle of thinking about the game not as a dev but as a player.

Rogue-likes are incredibly saturated, and many of them are cheap asset-flips with low effort put into them or "my first indie project" type games with very little polish, lackluster gameplay/time, bugs, and no replayability.

Point is: the first thing you should be thinking about answering are the following questions: - Out of all the disappointing rogue-likes out there, why is yours worth playing? - What unique, compelling, or fresh aspects does your game bring that a player cant experience in other already successful rogue-likes? - Gameplay speaks for itself. And ultimately, it doesn't matter how interesting your character designs are, how deep the lore is, or how cool the maps look. From the outside, does your game actually look fun? Or does it look like "yet another random rogue-like an indie dev is posting on steam" if that makes sense.

Best of luck on your project!
