“Soul Jar” by Paul Hart.
“[This game is] about [an] evolving AI[,] [a] robot that collects and imitates lifeforms, a “soul jar” from space, crash lands and must return to his ship. Along the way you teach it how to behave and depending how you influence and evolve his AI will result in several different endings.”
The core concept is so goddamn great. You can be careful about the robot, help him out of pits, pick him up and carry him along, or you can be aggressive and the machine will learn those character traits from you. The icing on the cake for me is the great pixel art of “Soul Jar”. Give it a try. >>PLAY
