A downloadable game
Normally I have problems with "artsy-fartsy" games. So I made one.
I made Color Palette to instill timidness in players. Players are presented with multiple colors and can chose between them by moving. Each choice makes new similar colors appear, and closes off access to the opposing color on the RGB scale. Players slowly carve their own irreversible path. I want to test if players recognize these ambiguous visuals as their own life choices or priorities and the doors that have been opened or closed in their life.
Ultimately it was too abstract, but once I explained this test to people, they found the experience very introspective.
