Thanks for taking the time to answer my questions! Yeah, I can see how the personality system could take a lot of time and effort, better not overwork yourself and end up with a burnout, take care :)
About the AI: Though I'm strongly against it, that is mostly because it usually takes away all personality and uniqueness from art, which doesn't seem to happen so much in this case, the game is still very charming despite of it. Hope you can one day get more artists to help you, if I were one I'd offer to help for free. Also, the sprites you did make were really nice!
