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.

Projects that use a Hexagonal Grid. Cells that have 6 sides.

Games where you have to manage resources in order to complete objectives. 

Focused on using its text, moreso than its visuals or audio, to tell the bulk of its story/plot. (Still can have great audio and visuals, though!)
