itch.io

Uses two-dimensional "sprites", 2D images created and used on a flat plane, as opposed to the three-dimensional models or environments found in 3D games.

Set in a fictional universe, often (but not always) with fantastic or supernatural elements, alternate worlds, magic and monsters.

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

Also known as TTRPG, tabletop role-playing games are tabletop games when you play a character within a set of rules. Typically actions are determined by speech and checked for success via dice rolls.
