As the artist for Last Courier (https://voidsway.itch.io/last-c If you wanna check it out) I regret not comparing the assets before creating them. I had them all in separate files and it made the game look pretty ununified stylistically and color-wise. I think I did pretty okay for my first game, and its decently fun, I'm just going to make sure I make my games more consistent in the future.
