itch.io

Games that challenge the player with critical thinking to solve levels. 

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.

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

A perspective where the camera is placed directly above the player. Common in 2D games, but can also be used in 3D games.
