Drew a perky little red thing and then my dog started yelling at another dog outside, thus ruining the immersion. Cauldi still looks a bit sketchy but I can excuse that because you were likely focused on making sure everything worked instead of looking polished.
A gallery feature or an PM feature similar to the Drawing Grounds is an obvious feature to add, but that's a whole other coding challenge that goes beyond simply making a pseudo art software. Good luck with your future projects in Godot, internet guy.
