itch.io

Role-playing games let you assume the role of a protagonist, customizing their abilities, equipment, and appearances. Through exploration, dialogue, and strategic combat, players navigate worlds, uncover lore, complete missions, and level up their characters.

Typically a graphical style where there are one two colors. (A bit can be either on or off, so two options) Commonly black and white, but can be any combination depending on the style the creator is trying to accomplish. 

Pretty sure everything is indie on itch.io but just in case you want something extra indie.
